trim
<?php
// Custom function returns a string with the first word in a bigger fontsize, with a default of 22px.

This will yield <b style="font-size: 22px;">Hello</b> World, I am a bouncy castle!
ucfirst
(PHP 4, PHP 5)
ucfirst — Make a string's first character uppercase
Description
string ucfirst
( string
$str
)
Returns a string with the first character of
str capitalized, if that character is
alphabetic.
Note that 'alphabetic' is determined by the current locale. For instance, in the default "C" locale characters such as umlaut-a (ä) will not be converted.
Parameters
-
str -
The input string.
Return Values
Returns the resulting string.
Examples
Example #1 ucfirst() example
<?php
$foo = 'hello world!';
$foo = ucfirst($foo); // Hello world!
$bar = 'HELLO WORLD!';
$bar = ucfirst($bar); // HELLO WORLD!
$bar = ucfirst(strtolower($bar)); // Hello world!
?>

A proper Turkish solution;
<?php
function ucfirst_turkish($str) {
$tmp = preg_split("//u", $str, 2, PREG_SPLIT_NO_EMPTY);
return mb_convert_case(
str_replace("i", "İ", $tmp[0]), MB_CASE_TITLE, "UTF-8").
$tmp[1];
}
$str = "iyilik güzelLİK";
echo ucfirst($str) ."\n"; // Iyilik güzelLİK
echo ucfirst_turkish($str); // İyilik güzelLİK
?>

Turkish solution:
<?php
mb_internal_encoding("UTF-8");
mb_regex_encoding("UTF-8");
function tr_ilkbuyuk($text)
{
$text = str_replace("I","ı",$text);
$text = mb_strtolower($text, 'UTF-8');
if($text[0] == "i")
$tr_text = "İ".substr($text, 1);
else
$tr_text = mb_convert_case($text, MB_CASE_TITLE, "UTF-8");
return trim($tr_text);
}
function tr_ucwords($text)
{
$p = explode(" ",$text);
if(is_array($p))
{
$tr_text = "";
foreach($p AS $item)
$tr_text .= " ".tr_ilkbuyuk($item);
return trim($tr_text);
}
else
return tr_ilkbuyuk($text);
}
$deger = "ıişllşlsdg";
echo tr_ucwords($deger);

if you want to ucfirst for utf8 try this one:
<?php
function ucfirst_utf8($stri){
if($stri{0}>="\xc3")
return (($stri{1}>="\xa0")?
($stri{0}.chr(ord($stri{1})-32)):
($stri{0}.$stri{1})).substr($stri,2);
else return ucfirst($stri);
}
?>
It is quick, not language (but utf8) dependend and does not use any mb-functions such as mb_ucfirst.

For those who want a multibyte-compliant ucfirst() without wanting to mess with encodings, this should do the trick:
<?php
function mb_ucasefirst($str){
$str[0] = mb_strtoupper($str[0]);
return $str;
}
?>

for anyone wanting to ucfirst each word in a sentence this works for me:

For lithuanian text with utf-8 encoding I use two functions (thanks [mattalexxpub at gmail dot com] and Svetoslav Marinov)
<?php
function my_ucfirst($string, $e ='utf-8') {
if (function_exists('mb_strtoupper') && function_exists('mb_substr') && !empty($string)) {
$string = mb_strtolower($string, $e);
$upper = mb_strtoupper($string, $e);
preg_match('#(.)#us', $upper, $matches);
$string = $matches[1] . mb_substr($string, 1, mb_strlen($string, $e), $e);
}
else {
$string = ucfirst($string);
}
return $string;
}
function sentence_case($string) {
$sentences = preg_split('/([.?!]+)/', $string, -1, PREG_SPLIT_NO_EMPTY|PREG_SPLIT_DELIM_CAPTURE);
$new_string = '';
foreach ($sentences as $key => $sentence) {
$new_string .= ($key & 1) == 0?
my_ucfirst(strtolower(trim($sentence))) :
$sentence.' ';
}
return trim($new_string);

This is what I use for converting strings to sentence case:
<?php
function sentence_case($string) {
$sentences = preg_split('/([.?!]+)/', $string, -1, PREG_SPLIT_NO_EMPTY|PREG_SPLIT_DELIM_CAPTURE);
$new_string = '';
foreach ($sentences as $key => $sentence) {
$new_string .= ($key & 1) == 0?
ucfirst(strtolower(trim($sentence))) :
$sentence.' ';
}
return trim($new_string);
}
print sentence_case('HMM. WOW! WHAT?');
// Outputs: "Hmm. Wow! What?"

I believe that mb_ucfirst will be soon added in PHP, but for now this could be useful
<?php
if (!function_exists('mb_ucfirst') && function_exists('mb_substr')) {
function mb_ucfirst($string) {
$string = mb_strtoupper(mb_substr($string, 0, 1)) . mb_substr($string, 1);
return $string;
}
}
?>
it also check is mb support enabled or not

Here's a function to capitalize segments of a name, and put the rest into lower case. You can pass the characters you want to use as delimiters.
i.e. <?php echo nameize("john o'grady-smith"); ?>
returns John O'Grady-Smith
<?php
function nameize($str,$a_char = array("'","-"," ")){
//$str contains the complete raw name string
//$a_char is an array containing the characters we use as separators for capitalization. If you don't pass anything, there are three in there as default.
$string = strtolower($str);
foreach ($a_char as $temp){
$pos = strpos($string,$temp);
if ($pos){
//we are in the loop because we found one of the special characters in the array, so lets split it up into chunks and capitalize each one.
$mend = '';
$a_split = explode($temp,$string);
foreach ($a_split as $temp2){
//capitalize each portion of the string which was separated at a special character
$mend .= ucfirst($temp2).$temp;
}
$string = substr($mend,0,-1);
}
}
return ucfirst($string);
}
?>

Inspired by the lcfirst function a simple mb_lcfirst to cope with multibyte strings:
<?php
function mb_lcfirst($str, $enc = null)
{
if($enc === null) $enc = mb_internal_encoding();
return mb_strtolower(mb_substr($str, 0, 1, $enc), $enc).mb_substr($str, 1, mb_strlen($str, $enc), $enc);
}

Changing the case can only be done by understanding the text. Take for example "USA", "Sunday", "March", "I am ...", abbreviations like "prob." and so on.

One thing I would do to make this more unviersally work would be to add strtolower() around your $sentence. Doing this will allow you to convert an all caps text block as well as an all lowercase text block.
<?php
function sentence_cap($impexp, $sentence_split) {
$textbad=explode($impexp, $sentence_split);
$newtext = array();
foreach ($textbad as $sentence) {
$sentencegood=ucfirst(strtolower($sentence));
$newtext[] = $sentencegood;
}
$textgood = implode($impexp, $newtext);
return $textgood;
}
$text = "this is a sentence. this is another sentence! this is the fourth sentence? no, this is the fourth sentence.";
$text = sentence_cap(". ",$text);
$text = sentence_cap("! ",$text);
$text = sentence_cap("? ",$text);
echo $text; // This is a sentence. This is another sentence! This is the fourth sentence? No, this is the fourth sentence.
?>

@ zee: this should solve your !, ?, and any punctuations you want to add. It can probably be cleaned up a bit.
<?php
function sentence_cap($impexp, $sentence_split) {
$textbad=explode($impexp, $sentence_split);
$newtext = array();
foreach ($textbad as $sentence) {
$sentencegood=ucfirst($sentence);
$newtext[] = $sentencegood;
}
$textgood = implode($impexp, $newtext);
return $textgood;
}
$text = "this is a sentence. this is another sentence! this is the fourth sentence? no, this is the fourth sentence.";
$text = sentence_cap(". ",$text);
$text = sentence_cap("! ",$text);
$text = sentence_cap("? ",$text);
echo $text; // This is a sentence. This is another sentence! This is the fourth sentence? No, this is the fourth sentence.

Another way to capitalize first letter of every sentence in a text, I hope it will help someone. It won't convert non-English characters, though, and ignores sentences ending with ! or ? etc.
<?php
$text="this is a sentence. this is another sentence.";
$split=explode(". ", $text);
foreach ($split as $sentence) {
$sentencegood=ucfirst($sentence);
$text=str_replace($sentence, $sentencegood, $text);
}
echo $text; // This is a sentence. This is another sentence.

Some simple function for cyrillic and latin letters both:
function rucfirst($str) {

else
return chr(ord(substr($str,0,1))-32).substr($str,1);
}

This is what you would expect php to deliver if there was a built-in function named ucsentence.
function ucsentence ($string){
$string = explode ('.', $string);
$count = count ($string);
for ($i = 0; $i < $count; $i++){
$string[$i] = ucfirst (trim ($string[$i]));
if ($i > 0){
$string[$i] = ' ' . $string[$i];
}
}
$string = implode ('.', $string);
return $string;

A combination of the below functions to enable ucfirst for multibyte strings in a shared hosting environment (where you can not always count on mbstring to be installed):

return $fc.mb_substr($str, 1, mb_strlen($str, $e), $e);
}
else {

plemieux' function did not work for me without passing the encoding to every single mb function (despite ini_set('default_charset', 'utf-8') at the top of the script). This is the example that works in my application (PHP 4.3):
<?php
function my_mb_ucfirst($str, $e='utf-8') {
$fc = mb_strtoupper(mb_substr($str, 0, 1, $e), $e);
return $fc.mb_substr($str, 1, mb_strlen($str, $e), $e);

This is a simple code to get all the 'bad words', stored in a database, out of the text. You could use str_ireplace but since that's installed on PHP5 only, this works as well. It strtolowers the text first then places capitals with ucfirst() where it thinks a capital should be placed, at a new sentence. The previous sentence is ended by '. ' then.
<?php
function filter($text){
$filters=mysql_query("SELECT word,result FROM filter");
while($filter=mysql_fetch_array($filters)){
$text=str_replace($filter[word],$filter[result],strtolower($text));
$parts=explode(". ",$text);
for($i=0;$i<count($parts);$i++){
$parts[$i]=ucfirst($parts[$i]);
}
$text=implode(". ",$parts);
}
return $text;
}
?>
12-Mar-2005 05:11
Ah, the last code were spoiled, here is the fixed one:
<?php
function uc_first($str){
$str[0] = strtr($str,
"abcdefghijklmnopqrstuvwxyz".
"\x9C\x9A\xE0\xE1\xE2\xE3".
"\xE4\xE5\xE6\xE7\xE8\xE9".
"\xEA\xEB\xEC\xED\xEE\xEF".
"\xF0\xF1\xF2\xF3\xF4\xF5".
"\xF6\xF8\xF9\xFA\xFB\xFC".
"\xFD\xFE\xFF",
"ABCDEFGHIJKLMNOPQRSTUVWXYZ".
"\x8C\x8A\xC0\xC1\xC2\xC3\xC4".
"\xC5\xC6\xC7\xC8\xC9\xCA\xCB".
"\xCC\xCD\xCE\xCF\xD0\xD1\xD2".
"\xD3\xD4\xD5\xD6\xD8\xD9\xDA".
"\xDB\xDC\xDD\xDE\x9F");
return $str;
}
?>
So, this function changes also other letters into uppercase, ucfirst() does only change: a-z to: A-Z.

This function does not work as expected with characters from non-English alphabets (I only tested it with scandinavian letters, => ). It leaves them as lowercase.
Someone already commented that the function doesn't work on html entities, which is somewhat understandable. This bug however takes place before I convert the strings to html.

Note: the return for this function changed in versions 4.3 when a string is passed of length 0. In <4.2 false is returned and in >4.3 a string of length 0 is returned.
Example:
$name = ucfirst("");
var_dump($name);
$name = ucfirst("owen");
var_dump($name);
Results for <4.2:
bool(false) string(4) "Owen"
Results for >4.3:
string(0) "" string(4) "Owen"

In the event you sort of need multiple delimiters to apply the same action to, you can preg_replace this "second delimiter" enveloping it with your actual delimiter.
A for instance, would be if you wanted to use something like Lee's FormatName function in an input box designed for their full name as this script was only designed to check the last name as if it were the entire string. The problem is that you still want support for double-barreled names and you still want to be able to support the possibility that if the second part of the double-barreled name starts with "mc", that it will still be formatted correctly.
This example does a preg_replace that surrounds the separator with your actual delimiter. This is just a really quick alternative to writing some bigger fancier blah-blah function. If there's a shorter, simpler way to do it, feel free to inform me. (Emphasis on shorter and simpler because that was the whole point of this.) :D
Here's the example. I've removed Lee's comments as not to confuse them with my own.
<?php
function FormatName($name=NULL)
{
if (empty($name))
return false;
$name = strtolower($name);
$name = preg_replace("[\-]", " - ",$name); // Surround hyphens with our delimiter so our strncmp is accurate
if (preg_match("/^[a-z]{2,}$/i",$name)) // Simple preg_match if statement
{
$names_array = explode(' ',$name); // Set the delimiter as a space.
for ($i = 0; $i < count($names_array); $i++)
{
if (strncmp($names_array[$i],'mc',2) == 0 || ereg('^[oO]\'[a-zA-Z]',$names_array[$i]))
{
$names_array[$i][2] = strtoupper($names_array[$i][2]);
}
$names_array[$i] = ucfirst($names_array[$i]);
}
$name = implode(' ',$names_array);
$name = preg_replace("[ \- ]", "-",$name); // Remove the extra instances of our delimiter
return ucwords($name);
}
}

Here's a function I threw together when needing to validate name entries (both first name and last name).
This allows simple formatting for names prefixed with "Mc" (like McDonald, McCulloch, etc) and names prefixed with O (like O'Reilly, O'Conner, etc)..
It also allows double-barrelled names to be formatted correctly, in the Smith-Jones way.
Here's the function...
<?php
function FormatName($name=NULL) {
/* Formats a first or last name, and returns the formatted
version */
if (empty($name))
return false;
// Initially set the string to lower, to work on it
$name = strtolower($name);
// Run through and uppercase any multi-barrelled names
$names_array = explode('-',$name);
for ($i = 0; $i < count($names_array); $i++) {
// "McDonald", "O'Conner"..
if (strncmp($names_array[$i],'mc',2) == 0 || ereg('^[oO]\'[a-zA-Z]',$names_array[$i])) {
$names_array[$i][2] = strtoupper($names_array[$i][2]);
}
// Always set the first letter to uppercase, no matter what
$names_array[$i] = ucfirst($names_array[$i]);
}
// Piece the names back together
$name = implode('-',$names_array);
// Return upper-casing on all missed (but required) elements of the $name var
return ucwords($name);
}
?>
If you have any other "rules" to follow for international/foreign naming rules, you can add them to the foreach loop, and it should still follow all of the other rules.
It's a quick fix, but it seems to do the job nicely.
Examples...
<?php
$name = "o'cONNER-MCdOnAld";
echo FormatName($name);
?>
Returns: O'Conner-McDonald

Here is a handy function that makes the first letter of everything in a sentence upercase. I used it to deal with titles of events posted on my website ... I've added exceptions for uppercase words and lowercase words so roman numeral "IV" doesn't get printed as "iv" and words like "a" and "the" and "of" stay lowercase.
function RemoveShouting($string)
{
$lower_exceptions = array(
"to" => "1", "a" => "1", "the" => "1", "of" => "1"
);
$higher_exceptions = array(
