strptime

(PHP 5 >= 5.1.0, PHP 7)

strptime Interpreta uma hora/data gerada pela função strftime()

Descrição

array strptime ( string $date , string $format )

strptime() retorna um array com a interpretação de date , ou FALSE em caso de erro.

Nomes de meses e semanas, e outras strings que dependem do idioma, respeitam o idioma corrente definido com a função setlocale() (LC_TIME).

Parâmetros

date (string)

A string a ser interpretada (retornada da função strftime()).

format (string)

O formato utilizado em date (o mesmo utilizado na função strftime()). Note que algumas opções de formato disponíveis na função strftime() podem não ter nenhum efeito com strptime(); o subconjunto exato que é suportado vai variar por ser baseado no sistema operacional e biblioteca C em uso.

Para mais informações sobre as opções de formato, veja a página da função strftime().

Valor Retornado

Retorna um array ou FALSE em caso de falha.

Os seguintes parâmetros são retornados no array
Parâmetro Descrição
"tm_sec" Segundos após o minuto (0-61)
"tm_min" Minutos após a hora (0-59)
"tm_hour" Horas passadas desde a meia-noite (0-23)
"tm_mday" Dia do mês (1-31)
"tm_mon" Meses passados desde janeiro (0-11)
"tm_year" Anos passados desde 1900
"tm_wday" Dias passados desde Sunday (0-6)
"tm_yday" Dias passados desde January 1 (0-365)
"unparsed" A parte date que não foi reconhecida usando o format especificado

Exemplos

Exemplo #1 Exemplo da função strptime()

<?php
$format 
'%d/%m/%Y %H:%M:%S';
$strf strftime($format);

echo 
"$strf\n";

print_r(strptime($strf$format));
?>

O exemplo acima irá imprimir algo similar à:

03/10/2004 15:54:19

Array
(
    [tm_sec] => 19
    [tm_min] => 54
    [tm_hour] => 15
    [tm_mday] => 3
    [tm_mon] => 9
    [tm_year] => 104
    [tm_wday] => 0
    [tm_yday] => 276
    [unparsed] =>
)

Notas

Nota: esta função não é implementada na plataforma Windows

Nota:

Internamente, esta função chama a função strptime() presente na biblioteca C do sistema. Esta função pode apresentar um comportamento diferente entre diferentes sistemas operacionais. A utilização da função date_parse_from_format(), que não é afetada por esta questão, é recomendada em versões do PHP 5.3.0 e superiores.

Nota:

"tm_sec" inclui todos os segundos do ano bissexto (atualmente 2 por ano). Para mais informações sobre segundos do ano bissexto, veja o » o artigo da Wikipedia sobre segundos Bissexto.

Nota:

Em versões anteriores ao PHP 5.2.0, a função poderia ter um comportamento inesperado. Excepcionalmente, as entradas "tm_sec", "tm_min" e "tm_hour" poderiam ser retornadas como valores indefinidos.

Be careful: the output of strptime() ( http://www.php.net/manual/en/function.strptime.php ) cannot always be used with mktime() ( http://www.php.net/manual/en/function.mktime.php )!

This is not because of what platform you're using or what format strings glibc supports. This is simply because strptime returns years SINCE 1900 (as documented above) and mktime expects a year in the format returned by date('Y') - which is the full 4 digits.

Therefore, if you parse a date with strptime and want to give it to mktime, you have to pass in ($parsed_time['tm_year'] + 1900) as the year parameter to mktime(), not just $parsed_time['tm_year'].

This issue arose when I had a date like: 19/06/2012 12:03:34. strtotime() doesn't parse this particular format, so I needed custom parsing. So I ended up with:
1. $ts = $service->getNeededDateTime();
2. $ts = strptime($ts, '%d/%m/%Y %H:%M:%S');
3. $ts = mktime($ts['tm_hour'], $ts['tm_min'], $ts['tm_sec'],
      $ts['tm_mon'], $ts['tm_mday'], ($ts['tm_year'] + 1900));

emanuil's comment / mktime() example is wrong, in that his mktime() line should have $ts['tm_mon'] + 1 because strptime() returns the months zero-based, while mktime() expects it one-based.

If you want to parse a date or a /time in windows env, i re-write strptime function for windows.

I use the same param and i return the same think that the original one.
I use sscanf to parde the string.
Only some format can be parsed (%S, %M, %H, %d, %m, %Y)

See this page (because the function is too big for this notes)
http://sauron.lionel.free.fr/?page=php_lib_strptime

If strptime() fails to match all of the format string and therefore an error occurred the function returns NULL.

The result of strptime() is not affected by the current timezone setting, even though strftime() is. Tested in PHP 5.1.6.

It says "Parse a time/date generated with strftime()" but that's not entirely correct -- While strptime("2006131", "%Y%W%u") works as expected, strptime("2006131", "%G%V%u") returns false instead of reversing the equivalent - and unambiguous - strftime() usage.  I suspect that's because glibc doesn't support that.  Anyway, this docu page fails to mention that apparently not all format components supported by strftime() can be used with strptime().

the example (or the function) has an inconsistancy with other PHP functions.

the example returns 104 for the year 2004

while in the strftime function the 2 digit year is 70-100 for 1970-2000
and 1-69 for 2001-2069

On some systems, particularly those of BSD lineage (such as FreeBSD and MacOS X), the tm_wday and tm_yday fields are only initialized if requested explicitly (that is, if the %a/%A/%u/%w and %j formats are specified), while others such as Linux and Solaris will calculate them automatically.

For Windows user! It's rather the same as strptime!
It uses the previous function: but call strToTime($date, $format) to strToDate($date, $format) because this name is forgiven!

<?php
function strToDateTime($date, $format) {
    if(!(
$date = strToDate($date, $format))) return;
   
$dateTime = array('sec' => 0, 'min' => 0, 'hour' => 0, 'day' => 0, 'mon' => 0, 'year' => 0, 'timestamp' => 0);
    foreach(
$date as $key => $val) {
        switch(
$key) {
            case
'd':
            case
'j': $dateTime['day'] = intval($val); break;
            case
'D': $dateTime['day'] = intval(date('j', $val)); break;
           
            case
'm':
            case
'n': $dateTime['mon'] = intval($val); break;
            case
'M': $dateTime['mon'] = intval(date('n', $val)); break;
           
            case
'Y': $dateTime['year'] = intval($val); break;
            case
'y': $dateTime['year'] = intval($val)+2000; break;
           
            case
'G':
            case
'g':
            case
'H':
            case
'h': $dateTime['hour'] = intval($val); break;
           
            case
'i': $dateTime['min'] = intval($val); break;
           
            case
's': $dateTime['sec'] = intval($val); break;
        }
    }
   
$dateTime['timestamp'] = mktime($dateTime['hour'], $dateTime['min'], $dateTime['sec'], $dateTime['mon'], $dateTime['day'], $dateTime['year']);

$dateTime;

If you need strptime but are restricted to a php version which does not support it (windows or before PHP 5), note that MySQL since Version 4.1.1 offers (almost?) the same functionality with the STR_TO_DATE function.
