ucwords

(PHP 4, PHP 5)

ucwords Converte in maiuscolo il primo carattere di ogni parola di una stringa

Descrizione

string ucwords ( string $str )

Restituisce un testo in cui la lettera iniziale di ogni parola è convertita in maiuscolo, se il carattere è alfabetico.

Definizione di parola: sequenza di caratteri immediatamente seguita da un carattere di delimitazione (i delimitatori sono: spazio, form-feed, newline, carriage return, tab orizzontale e tab verticale).

Example #1 Esempio di uso di ucwords()

<?php
$foo 
'hello world!';
$foo ucwords($foo);             // Hello World! 

$bar 'HELLO WORLD!';
$bar ucwords($bar);             // HELLO WORLD!
$bar ucwords(strtolower($bar)); // Hello World!
?>

Nota: Questa funzione è binary-safe (gestisce correttamente i file binari)

Vedere anche strtoupper(), strtolower() e ucfirst().

My quick and dirty ucname (Upper Case Name) function.

<?php
//FUNCTION

function ucname($string) {
   
$string =ucwords(strtolower($string));

    foreach (array(
'-', '\'') as $delimiter) {
      if (
strpos($string, $delimiter)!==false) {
       
$string =implode($delimiter, array_map('ucfirst', explode($delimiter, $string)));
      }
    }
    return
$string;
}
?>
<?php
//TEST

$names =array(
 
'JEAN-LUC PICARD',
 
'MILES O\'BRIEN',
 
'WILLIAM RIKER',
 
'geordi la forge',
 
'bEvErly CRuSHeR'
);
foreach (
$names as $name) { print ucname("{$name}\n"); }

//PRINTS:
/*
Jean-Luc Picard
Miles O'Brien
William Riker
Geordi La Forge
Beverly Crusher
*/
?>

You can add more delimiters in the for-each loop array if you want to handle more characters.

"ieure at php dot net", your idea is pure poetry!

The function below will standardize the capitalization on people's names and the titles of reports and essays . You may need to adapt the lists in "$all_uppercase" and "$all_lowercase" to suit the data that you are working with.

function my_ucwords($str, $is_name=false) {
   // exceptions to standard case conversion
   if ($is_name) {
       $all_uppercase = '';
       $all_lowercase = 'De La|De Las|Der|Van De|Van Der|Vit De|Von|Or|And';
   } else {
       // addresses, essay titles ... and anything else
       $all_uppercase = 'Po|Rr|Se|Sw|Ne|Nw';
       $all_lowercase = 'A|And|As|By|In|Of|Or|To';
   }
   $prefixes = 'Mc';
   $suffixes = "'S";

   // captialize all first letters
   $str = preg_replace('/\\b(\\w)/e', 'strtoupper("$1")', strtolower(trim($str)));

   if ($all_uppercase) {
       // capitalize acronymns and initialisms e.g. PHP
       $str = preg_replace("/\\b($all_uppercase)\\b/e", 'strtoupper("$1")', $str);
   }
   if ($all_lowercase) {
       // decapitalize short words e.g. and
       if ($is_name) {
           // all occurences will be changed to lowercase
           $str = preg_replace("/\\b($all_lowercase)\\b/e", 'strtolower("$1")', $str);
       } else {
           // first and last word will not be changed to lower case (i.e. titles)
           $str = preg_replace("/(?<=\\W)($all_lowercase)(?=\\W)/e", 'strtolower("$1")', $str);
       }
   }
   if ($prefixes) {
       // capitalize letter after certain name prefixes e.g 'Mc'
       $str = preg_replace("/\\b($prefixes)(\\w)/e", '"$1".strtoupper("$2")', $str);
   }
   if ($suffixes) {
       // decapitalize certain word suffixes e.g. 's
       $str = preg_replace("/(\\w)($suffixes)\\b/e", '"$1".strtolower("$2")', $str);
   }
   return $str;
}

// A name example
print my_ucwords("MARIE-LOU VAN DER PLANCK-ST.JOHN", true);
// Output: Marie-Lou van der Planc-St.John

// A title example
print my_ucwords("to be or not to be");
// Output: "To Be or Not to Be"

Features:
- multi byte compatible
- handles multiple delimiters

<?php
function ucwords_specific ($string, $delimiters = '', $encoding = NULL)
{
    if (
$encoding === NULL) { $encoding = mb_internal_encoding();}

    if (
is_string($delimiters))
    {
       
$delimiters str_split( str_replace(' ', '', $delimiters));
    }

   
$delimiters_pattern1 = array();
   
$delimiters_replace1 = array();
   
$delimiters_pattern2 = array();
   
$delimiters_replace2 = array();
    foreach (
$delimiters as $delimiter)
    {
       
$uniqid = uniqid();
       
$delimiters_pattern1[]   = '/'. preg_quote($delimiter) .'/';
       
$delimiters_replace1[]   = $delimiter.$uniqid.' ';
       
$delimiters_pattern2[]   = '/'. preg_quote($delimiter.$uniqid.' ') .'/';
       
$delimiters_replace2[]   = $delimiter;
    }

   
// $return_string = mb_strtolower($string, $encoding);
   
$return_string = $string;
   
$return_string = preg_replace($delimiters_pattern1, $delimiters_replace1, $return_string);

   
$words = explode(' ', $return_string);

    foreach (
$words as $index => $word)
    {
       
$words[$index] = mb_strtoupper(mb_substr($word, 0, 1, $encoding), $encoding).mb_substr($word, 1, mb_strlen($word, $encoding), $encoding);
    }

   
$return_string = implode(' ', $words);

   
$return_string = preg_replace($delimiters_pattern2, $delimiters_replace2, $return_string);

    return
$return_string;
}
?>

Params:
1. string: The string being converted
2. delimiters: a string with all wanted delimiters written one after the other e.g. "-'"
3. encoding: Is the character encoding. If it is omitted, the internal character encoding value will be used.

Example Usage:
<?php
mb_internal_encoding
('UTF-8');
$string = "JEAN-PAUL d'artagnan şŠ-òÀ-éÌ hello - world";
echo
ucwords_specific( mb_strtolower($string, 'UTF-8'), "-'");
?>

Output:
Jean-Paul D'Artagnan Şš-Òà-Éì Hello - World

Correction to the code of firewire at itsyourdomain dot com:

preg_replace_callback('/\b(\w)(\w+)?/',
   create_function('$a',
   'return strtoupper($a[1]) . ((sizeof($a) > 2 ) ? 
       strtolower($a[2]) : "");'),
    'p.s.: hello.this is my string.');

Will work with punctuation as well as spaces.

UTF-8 Title Case that works for me even with hyphens involved!

$str = 'ĐaaČaa-AAAaaa, BBbb';

$str = mb_convert_case($str, MB_CASE_TITLE, "UTF-8");

echo($str): 'Đaačaa-Aaaaaa, Bbbb'

Some recipes for switching between underscore and camelcase naming:

<?php
// underscored to upper-camelcase
// e.g. "this_method_name" -> "ThisMethodName"
preg_replace('/(?:^|_)(.?)/e',"strtoupper('$1')",$string);

// underscored to lower-camelcase
// e.g. "this_method_name" -> "thisMethodName"
preg_replace('/_(.?)/e',"strtoupper('$1')",$string);

// camelcase (lower or upper) to underscored
// e.g. "thisMethodName" -> "this_method_name"
// e.g. "ThisMethodName" -> "this_method_name"
strtolower(preg_replace('/([^A-Z])([A-Z])/', "$1_$2", $string));
?>

Of course these aren't 100% symmetric.  For example...
  * this_is_a_string -> ThisIsAString -> this_is_astring
  * GetURLForString -> get_urlfor_string -> GetUrlforString

I did the same thing as Catalin, but for French names.

Here's what I'm doing :

For each word (not considering the single-quote as a word boundary character) :
- Put the word in lower case
- If the word is "de", return, else, put the first letter in upper-case
- See if the second character of the word is a single-quote
- Yes ? Put the next char in upper case
- And if the char before the single quote is D, put it back to lower case (-> d)

This complies with the French rules for capitalization in names.

Sample results :
-d'Afoo Bar
-de Foo Bar
-O'Foo Bar
-Foo'bar

<?php
function my_ucwords($s) {
       
$s = preg_replace_callback("/(\b[\w|']+\b)/s", fixcase_callback, $s);
       
        return
$s;        
       
    }
   
    function
fixcase_callback($word) {

       
$word = $word[1];
       
       
$word = strtolower($word);
       
        if(
$word == "de")
            return
$word;
       
       
$word = ucfirst($word);
       
        if(
substr($word,1,1) == "'") {
            if(
substr($word,0,1) == "D") {
               
$word = strtolower($word);
            }
           
$next = substr($word,2,1);
           
$next = strtoupper($next);
           
$word = substr_replace($word, $next, 2, 1);
        }
       
        return
$word;
    }

I have rewritten a UCSMART function adding a feature to translate special ASCII char (windows occidental ascii charset):

You can edit/add/delete char by use the first two string (be carefull to preserve the order of the string).

Enjoy!

<?
$ASCII_SPC_MIN
= "àáâãäåæçèéêëìíîïðñòóôõöùúûüýÿžš";
$ASCII_SPC_MAX = "ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖÙÚÛÜÝŸŽŠ";

function
str2upper($text) {
    global
$ASCII_SPC_MIN,$ASCII_SPC_MAX;
    return
strtr(strtoupper($text),$ASCII_SPC_MIN,$ASCII_SPC_MAX);
}
function
str2lower($text) {
    global
$ASCII_SPC_MIN,$ASCII_SPC_MAX;
    return
strtr(strtolower($text),$ASCII_SPC_MAX,$ASCII_SPC_MIN);
}
function
ucsmart($text) {
    global
$ASCII_SPC_MIN;
    return
preg_replace(
       
'/([^a-z'.$ASCII_SPC_MIN.']|^)([a-z'.$ASCII_SPC_MIN.'])/e',
       
'"$1".str2upper("$2")',
       
str2lower($text)
    );
}
?>

In the function ucsmart() posted by ieure at php dot net on 04-Dec-2005 11:57, I found a similar problem in this function to what he found in igua's.

<?php
function ucsmart($text)
{
   return
preg_replace('/([^a-z]|^)([a-z])/e', '"$1".strtoupper("$2")',
                      
strtolower($text));
}
?>

"igua's code adds a backslash in front of the first single quote for me. This doesn't alter the content in any way other than changing case."

Actually, it did end up changing the content for me (php 5.0.4) in the way that this function escapes a single quotation (apostrophe) in the MIDDLE of a word.

For example:

who's online?

Became:

Who\'s Online?

The fix is simple however, and merely requires fine-tuning the regular expression:

<?php
function ucsmart($text)
{
   return
preg_replace('/([^a-z\']|^)([a-z])/e', '"$1".strtoupper("$2")',
                      
strtolower($text));
}
?>

(note: while previewing this note before adding it, I am noticing php's website is not correctly displaying the change I made as I wrote it. After the first a-z in the expression, the single quotation should be escaped... If it isn't you will get a parse error! And apoligies if my text here is colored as php code; not my fault!)

This will not escape a single quotation mark which occurs in the middle of a word... Though, you may find that might need to add other characters inside the regular expression if you use other special characters inside your words and if you get funky output.

It's a great expression though! Simple, yet very powerful. Kudos!

Whoa guys, tone things down a bit here. No need to loop and implode. This is a one-line solution:

function ucsmart($text)
{
    return preg_replace('/([^a-z]|^)([a-z])/e', '"$1".strtoupper("$2")',
                        strtolower($text));
}

igua's code adds a backslash in front of the first single quote for me. This doesn't alter the content in any way other than changing case.

Recently i got a request from a client to make the first letter of any word in capital even they are separated by hyphen.

Eg : donzé pierre-yves      => Donzé Pierre-Yves
       joye-cagnard frédéric => Joye-Cagnard Frédéric

ucwords("donzé pierre-yves") can make it display
Donzé Pierre-yves but actually i need even the first letter of the second word to be in capital.

So in order to get this i have just written a function below and it works fine. But i hope there would be a better and easier way to do this if so kindly share.

<?php

$str
= "donzé pierre-yves";
echo
ucwordsHyphen($str); /*returns Donzé Pierre-Yves*/

function ucwordsHyphen($str){
                   
$converted_str = "";
                   
$str_array = explode(" ",$str);
                    foreach(
$str_array as $key=>$value):
                        if(
strpos($value, '-')):
                            
$value = str_replace("-", " ", $value);
                            
$value = ucwords(strtolower($value));
                            
$value = str_replace(" ", "-", $value);
                        else:
                           
$value = ucwords(strtolower($value));
                        endif;
                       
$converted_str .= " ".$value;
                    endforeach;
                   return
$converted_str;
            }
?>

Thanks.

Is more simple to use str_replace to use ucwords without using space as separator like:

<?php

function ucwordsEx($str, $separator){

     
$str = str_replace($separator, " ", $str);
     
$str = ucwords(strtolower($str));
     
$str = str_replace(" ", $separator, $str);
      return
$str;

}
/*
Example:
*/
echo ucwordsEx("HELLO-my-NAME-iS-maNolO", "-");
/*
Prints: "Hello My Name Is Manolo"
*/

?>

Relating to the mb_ucwords() function posted by Anonymous.  In order for this to actually be multi-byte compliant, you would also need to use mb_substr() and mb_strlen() instead of substr and strlen respectively.

Here it is corrected and extended even further to allow multiple word separators and a list of exceptions to correct after title casing. It's a bit tedious and inelegant, but things frequently are when dealing with human languages.

function mb_ucwords($str) {
    $exceptions = array();
    $exceptions['Hp'] = 'HP';
    $exceptions['Ibm'] = 'IBM';
    $exceptions['Gb'] = 'GB';
    $exceptions['Mb'] = 'MB';
    $exceptions['Cd'] = 'CD';
    $exceptions['Dvd'] = 'DVD';
    $exceptions['Usb'] = 'USB';
    $exceptions['Mm'] = 'mm';
    $exceptions['Cm'] = 'cm';
    //    etc.
   
    $separator = array(" ","-","+");
   
    $str = mb_strtolower(trim($str));
    foreach($separator as $s){
        $word = explode($s, $str);

        $return = "";
        foreach ($word as $val){
            $return .= $s . mb_strtoupper($val{0}) . mb_substr($val,1,mb_strlen($val)-1);
        }
        $str = mb_substr($return, 1);
    }

    foreach($exceptions as $find=>$replace){
        if (mb_strpos($return, $find) !== false){
            $return = str_replace($find, $replace, $return);
        }
    }
    return mb_substr($return, 1);

In response to joshuamallory at yahoo dot com:

Using CSS to fix a PHP fault is not the ideal way to solve a problem. CSS is browser dependent and can only be used when the data is presented in a web page. A better fix would be something like this:

<?php
function better_ucwords($string) {
  
$string = ucwords($string);
  
$string = preg_replace('#[\\/][a-z]#e', "strtoupper('$0')", $string);
   return
$string;
}

If you want to format a string like...

<?php
    $string
= "computer programming/repair";
    print
ucwords($string);
?>

Output: Computer Programming/repair

Notice the word after the slash (Programming/repair) isn't capitalized. To fix this, use CSS...

<?php
    $string
= "computer programming/repair";
    print
'<p style="text-transform:capitalize">';
    print
ucwords($string);
    print
'<p>';

    foreach ($temp as $key=>$word) {

$tmp[1];

Thanks a lot brother.

I tested it with a few variations. It works perfectly. Its really great and simple usage of the existing functions. It would be glad to all PHP folks and good to PHP if these kind of functions will be in PHP library on upcoming releases.

<?php

$name1
= "mark-yves robert";
$name2 = "mark-yves robert-bryan";

echo
'<br/>Name 1 (mark-yves robert) =>'.
ucwordspecific($name1,'-'); //returns Mark-Yves Robert

echo '<br/>Name 2 (mark-yves robert-bryan)

=>'
.ucwordspecific($name2,'-');
//returns Mark-Yves Robert-Bryan

function ucwordspecific($str,$delimiter){
$delimiter_space = '- ';
return
str_replace($delimiter_space,$delimiter,ucwords

(str_replace($delimiter,$delimiter_space,$str)));
}

?>

ucwords() only uses whitespace as a delimiter. I found that I needed the ability to use other delimiters for denoting words.

Example: Transforming "content-type" into "Content-Type".

<?php
/**
* Capitalize all words
* @param string Data to capitalize
* @param string Word delimiters
* @return string Capitalized words
*/
function capitalizeWords($words, $charList = null) {
   
// Use ucwords if no delimiters are given
   
if (!isset($charList)) {
        return
ucwords($words);
    }
   
   
// Go through all characters
   
$capitalizeNext = true;
   
    for (
$i = 0, $max = strlen($words); $i < $max; $i++) {
        if (
strpos($charList, $words[$i]) !== false) {
           
$capitalizeNext = true;
        } else if (
$capitalizeNext) {
           
$capitalizeNext = false;
           
$words[$i] = strtoupper($words[$i]);
        }
    }
   
    return
$words;
}
?>

Testing:
<?php
echo capitalizeWords('this is a test');  // This Is A Test
echo capitalizeWords('this-is-a-test');  // This-is-a-test
echo capitalizeWords('this is a test', ' ');  // This Is A Test
echo capitalizeWords('this-is-a-test', '-');  // This-Is-A-Test
echo capitalizeWords('this-is a-test', ' ');  // This-is A-test
echo capitalizeWords('this-is a-test', '-');  // This-Is a-Test
echo capitalizeWords('this-is a-test', ' -');  // This-Is A-Test
?>

When attempting to adopt a solution similar to Catalin's post (20-Oct-2008 10:14), I ran into some additional problems. Just a heads up, Catalin's wasn't capitalizing correctly when a name like "O'reilley" appeared at the start of the string or a new line. Also, it doesn't account for locale-sensitivity.

I also needed to recognize additional Irish surnames, such as "McArthur/MacArthur" or "FitzGerald". I also didn't want to misinterpret French as an Irish surname, so, "S'il vous plaît" shouldn't result in the "i" in "S'il" capitalized.

I modified Catalin's version, but it's still not perfect. This version happened to suit my needs, so be sure to assess your own needs before using.

<?php

function my_ucwords($str)
{
   
$str = ucwords($str);

   
// Not perfect
   
return preg_replace(
       
'/
            (?: ^ | \\b )         # assertion: beginning of string or a word boundary
            ( O\' | Ma?c | Fitz)  # attempt to match Irish surnames
            ( [^\W\d_] )          # match next char; we exclude digits and _ from \w
        /xe'
,
       
"'\$1' . strtoupper('\$2')",
       
$str);
}

ucwords for UTF-8 strings:

$str = mb_convert_case($str, MB_CASE_TITLE, "UTF-8");
    return (
$str);

Here is a function to capitalize a last name, accounting for hyphens, apostrophes, "Mc" and "Mac":

<?php
function CapitalizeLastName($name) {
   
$name = strtolower($name);
   
$name = join("'", array_map('ucwords', explode("'", $name)));
   
$name = join("-", array_map('ucwords', explode("-", $name)));
   
$name = join("Mac", array_map('ucwords', explode("Mac", $name)));
   
$name = join("Mc", array_map('ucwords', explode("Mc", $name)));
    return
$name;
}
?>

I speed tested it against functions that used preg_replace() with an "e" modifier, preg_replace_callback(), and a character-by-character parsing.  Unexpectedly, this function using join(), array_map() and explode() was fastest.

The code posted by neil doesn't fully do what is wanted. Try adding some more question marks at the end and it will return a not wanted string.

Below code will uppercase all your words regardless of the delimiter.

<?php
$text
= "What?No 'delimiters',shit \"happens\" here.this solves all problems???";
preg_match_all('/[A-Za-z]+|[^A-Za-z]+/', $text, $data);
for (
$i = 0; $i < count($data[0]); $i++) {
 
$data[0][$i] = ucfirst($data[0][$i]);
}
$text = implode("", $data[0]);
print
$text;
?>

This function will work on anything, not just words separated by spaces. (eg: 'ac/bc/dc,xc zz' => 'Ac/Bc/Dc,Xc Zz')

function ucwords_all($str) {
    return preg_replace_callback('/\b(\w)/', function($m) {
        return strtoupper($m[0]);
    }, $str);

This solution is a proper use of capitalize first letters of "TURKISH" sentence by ATÖLYE15 crew.

function ucwordstr($sentence)
{
        $letters = array('I','İ','Ç','Ş','Ü','Ö','Ğ');
        $replace = array('ı','i','ç','ş','ü','ö','ğ');

        $sentence = mb_strtolower(str_replace($letters,$replace,$sentence),"UTF-8");

        $words = array();

        foreach(explode(" ",$sentence) as $word)
        {
            $first = str_replace($replace,$letters,mb_substr($word, 0, 1, "UTF-8"));
            $other = mb_substr($word,1,strlen($word)-1,"UTF-8");

            $words[] = $first.$other;
        }

        $sentence = implode(" ",$words);

        return ucwords($sentence);

Its still possible to clean a bit more the previous sample:

$string=strtolower($string); $break=true;
for ($i=0; $i < strlen($string); $i++) { $subed=$string[$i];
if (((ord($subed) > 64) && (ord($subed) < 123)) || ((ord($subed) > 48) && (ord($subed) < 58))) {
if ($break) { $string[$i] = strtoupper($subed); }
$break=false; } else { $break=true; }
}

Because I needed a function that did the same as the function proper in Excel I created this little function :

<?php
function proper($string){
 
   
$string = strtolower($string);
   
   
$lettersAndNumbers = 'abcdefghijklmnopqrstuvwxyz01234565789';
   
   
$string[0] = strtoupper($string[0]);
   
    for (
$index = 1;$index < strlen($string);$index++){
      if (
strpos($lettersAndNumbers, $string[$index]) === false){
        if (
$index +1 < strlen($string)){
         
$string[$index+1] = strtoupper($string[$index+1]);
         
$index++;
        }
      }
    }
 
    return(
$string);
   
  }

The code posted above by Joerg Krause only works for a string which ends with one of the delimiters. A possible fix is:

<?php
$text
= "What?No delimiters,shit happens here.this solves all problems.";
preg_match_all("/(\w+[,. ?])+/U", $text, $words);
preg_match("/(\w+)$/", $text, $lastword);
$words[0][] = $lastword;
foreach(
$words[0] as $part) $uwords[] = ucfirst($part);
$text = implode("", $uwords);
echo
$text;

Another ucwords function with custom separator.

<?php
function ucwords_custom($str, $sep)
{
    return
preg_replace_callback('/' . preg_quote($sep) . './i', create_function(
       
'$match',
       
'return strtoupper($match[0][1]);'
   
), $str);
}
?>

or simpler with PHP5.3

<?php
function ucwords_custom2($str, $sep = ' ')
{
    return
preg_replace_callback('/' . preg_quote($sep) . './i', function($match) {
        return
strtoupper($match[0][1]);

I have looked for a work-around that would upper-case letter after an ' too.

For example,

ucword("o'lunney's");

would output "O'lunney's" and I wanted it to output "O'Lunney's".

Here is my function:

<?php
function my_ucwords($string) {
       
$string = ucwords(strtolower($string));
       
$string = preg_replace_callback("/( [ a-zA-Z]{1}')([a-zA-Z0-9]{1})/s",create_function('$matches','return $matches[1].strtoupper($matches[2]);'),$string);
        return
$string;
}
?>

Hope it helps someone.

I modified Q1712's code (below) to use regular expressions
instead of characters to properly capitalize words that fall
directly after an unwanted character. See his post for details.

This version allows me to use it around html elements, etc.

<?php
   
function my_ucwords($string){

       
$invalid_characters = array('"',
                                   
'\(',
                                   
'\[',
                                   
'\/',
                                   
'<.*?>',
                                   
'<\/.*?>');

        foreach(
$invalid_characters as $regex){
           
$string = preg_replace('/('.$regex.')/','$1 ',$string);
        }

       
$string=ucwords($string);

        foreach(
$invalid_characters as $regex){
           
$string = preg_replace('/('.$regex.') /','$1',$string);
        }

        return
$string;
    }
?>

Moreover, to get a proper title case, i combine it with this function:

This Function is obtained from:
http://codesnippets.joyent.com/posts/show/716

<?php
   
function title_case($title) {
       
$smallwordsarray = array(
           
'of','a','the','and','an','or','nor','but','is','if','then',
'else','when',
           
'at','from','by','on','off','for','in','out',
'over','to','into','with'
       
);

       
$words = explode(' ', $title);
        foreach (
$words as $key => $word)
        {
            if (
$key == 0 or !in_array($word, $smallwordsarray))
           
$words[$key] = $this->my_ucwords(strtolower($word));
        }

       
$newtitle = implode(' ', $words);
        return
$newtitle;
    }
?>
Hope you find it useful.

An improved of ucsentence. In fact its a function to avoid ugly data entry. It's based on code taken from this page. Can be inproved for better performance, of course...

3- split sentences not only with "." but also with "?" and "!"
4- Puts a white space at the begining of each sentence

Function to do what ucwords is intended to do - just correctly also for international char sets:

function mb_ucwords($s)
{
    $s = mb_strtolower(trim($s));
    $w = explode(" ", $s);
   
    $return = "";
    foreach ($w as $val)
    {
        $return .= " " . mb_strtoupper($val{0}) . substr($val,1,strlen($val)-1);
    }
    return trim($return);
}

Q1712 at online dot ms

ucwords() only excepts whitespace in front of a word, although some chars like '"' or '(' normally have no space between them and the following word:
<?php
$title
= 'ELVIS "THE KING" PRESLEY - (LET ME BE YOUR) TEDDY BEAR';
echo
ucwords(strtolower($title));
?>
prints: Elvis "the King" Presley - (let Me Be Your) Teddy Bear

To avoid this i use a small function adding and deleting blanks behind these chars, and using ucwords() in between:

<?php
function my_ucwords($string)
  {
   
$noletters='"([/'; //add more if u need to
   
for($i=0; $i<strlen($noletters); $i++)
     
$string = str_replace($noletters[$i], $noletters[$i].' ', $string);
   
$string=ucwords($string);
    for(
$i=0; $i<strlen($noletters); $i++)
     
$string = str_replace($noletters[$i].' ', $noletters[$i], $string);
    return
$string;
  }

$title = 'ELVIS "THE KING" PRESLEY - (LET ME BE YOUR) TEDDY BEAR';
echo
my_ucwords(strtolower($title));
?>

prints: Elvis "The King" Presley - (Let Me Be Your) Teddy Bear

ucwords that works also with apices: '
for example: "aquila d'abruzzo" became "Aquila d'Abruzzo"
The second part after the // comment can removed! Is optimized for italian language (leave lowercase articles, prepositions, conjunctions) but easily changeable. Notice che "'s"!! for example "hotel 2000's" becames "Hotel 2000's".

Before noticing this function I made the following function (that does the same as ucwords):

<?php
function firstUpper($string)
{
   
$string = str_replace(array("Æ","Ø","Å"), array("æ","ø","å"), strtolower($string));
   
$ord = explode(" ", $string);
   
   
$return = "";
    foreach (
$ord as $val)
    {

       
$return .= " " . str_replace(array("æ","ø","å"), array("Æ","Ø","Å"), strtoupper($val{0})) . substr($val,1,strlen($val)-1);
    }
    return
$return;
}
?>

It also converts Danish letters without using the setlocale function.

Response to arif:

We do not need that long functions. In order to make ucwords() worked properly in Turkish words that contain speacial characters, we can use the following command in our php codes:

setlocale(LC_ALL, 'tr_TR');

This will set locale to Turkish.

Here is a simple, yet winded, opposite to ucwords.

<?php
/*
    # lcwords v1.000
    # Convert the first word character to lowercase (opposite to ucwords)
    # input string
    # return string
*/
function lcwords($string)
{
   
/* Some temporary variables */
    #loop variable
   
$a = 0;
   
#store all words in this array to be imploded and returned
   
$string_new = array();
   
#create array of all words
   
$string_exp = explode(" ",$string);
    foreach(
$string_exp as $astring)
    {
        for(
$a=0;$a<strlen($astring);$a++)
        {
           
#check that the character we are at {pos $a} is a word
            #i.e. if the word was !A the code would fail at !
            #then loop to the next character and succeed at A
            #check at character position $a
           
if(preg_match("'\w'",$astring[$a]))
            {
               
$astring[$a] = strtolower($astring[$a]);
               
#end the loop
               
break;
            }
        }
       
$string_new[] = $astring;
    }
   
#recreate the string from array components using space deliminator
   
return implode(" ",$string_new);
}
?>

Of course a simplier way would be to use a callback, but I like working with long code :)

Here's a  piece that allows you to use the contents of a directory..  capitalizes the words and make links.. this particular example splits file names at _ and only selects file with .htm extensions (thought you could use any extension and call it using  include()  or soom such)
ie my_file_name.htm will produce
<a href="my_file_name.htm">My File Name</a>

<?php
$path
= "/home/path/to/your/directory";
  
$mydir = dir($path);
   while((
$file = $mydir->read()) !== false) {
     if(
substr($file, -4)=='.htm'){
   
$trans = array("_" => " ", ".htm" => ""); // creates the editing array
   
$newlist = strtr($file, $trans); // edits using editing array

A function knowing about name case (i.e. caps on McDonald etc)

function name_case($name)
{
    $newname = strtoupper($name[0]);   
    for ($i=1; $i < strlen($name); $i++)
    {
        $subed = substr($name, $i, 1);    
        if (((ord($subed) > 64) && (ord($subed) < 123)) ||
            ((ord($subed) > 48) && (ord($subed) < 58)))
        {
            $word_check = substr($name, $i - 2, 2);
            if (!strcasecmp($word_check, 'Mc') || !strcasecmp($word_check, "O'"))
            {
                $newname .= strtoupper($subed); 
            }
            else if ($break)
            {
               
                $newname .= strtoupper($subed);
            }
            else      
            {
                $newname .= strtolower($subed);
            }
             $break=0;
        }
        else
        {
            // not a letter - a boundary
             $newname .= $subed;
            $break=1;
        }
    }   
    return $newname;
