strptime

(PHP 5 >= 5.1.0)

strptime — Analyse une date générée par strftime()

Description

array strptime ( string $date , string $format )

strptime() retourne un tableau après avoir analysé date , ou FALSE en cas d'erreur.

Les noms des mois et jours de la semaine dépendent de la configuration locale, choisie avec setlocale() (LC_TIME).

Liste de paramètres

date (string)

La chaîne à analyser (e.g. retourné par strftime())

format (string)

Le format utilisé par date (e.g. le même que celui qui a été utilisé par strftime()).

Pour plus d'informations sur les spécificateurs de formats, voyez la fonction strftime().

Valeurs de retour

Retourne un tableau, ou FALSE en cas d'erreur.

**Les paramètres suivants sont retournés dans le tableau**
Paramètre	Description
tm_sec	Secondes après la minute (0-61)
tm_min	Minutes après l'heure (0-59)
tm_hour	Heure depuis minuit (0-23)
tm_mday	Jour du mois (1-31)
tm_mon	Mois depuis janvier (0-11)
tm_year	Années depuis 1900
tm_wday	Jours depuis dimanche (0-6)
tm_yday	Jours depuis le 1er janvier (0-365)
unparsed	La partie de `date` qui n'a pas été reconnue par l'analyseur avec le `format` spécifié.

Exemples

Exemple #1 Exemple avec strptime()


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

echo "$strf\n";

print_r(strptime($strf, $format));
?>

L'exemple ci-dessus va afficher quelque chose de similaire 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] =>
)

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']);

    return $dateTime;

}

?>

It's not the same as strptime. The array keys are different, for example '%d' will produce 'd' => '12'!!!

But it also returns false on failure.



<?php



function strToTime($date, $format) {

    $search = array('%d', '%D', '%j', // day

                    '%m', '%M', '%n', // month

                    '%Y', '%y', // year

                    '%G', '%g', '%H', '%h', // hour

                    '%i', '%s');

    $replace = array('(\d{2})', '(\w{3})', '(\d{1,2})', //day

                     '(\d{2})', '(\w{3})', '(\d{1,2})', // month

                     '(\d{4})', '(\d{2})', // year

                     '(\d{1,2})', '(\d{1,2})', '\d{2}', '\d{2}', // hour

                     '(\d{2})', '(\d{2})');

    

    $pattern = str_replace($search, $replace, $format);

    

    if(!preg_match("#$pattern#", $date, $matches)) {

        return false;

    }

    $dp = $matches;

    

    if(!preg_match_all('#%(\w)#', $format, $matches)) {

        return false;

    }

    $id = $matches['1'];



    if(count($dp) != count($id)+1) {

        return false;

    }



    $ret = array();

    for($i=0, $j=count($id); $i<$j; $i++) {

        $ret[$id[$i]] = $dp[$i+1];

    }



    return $ret;

}

?>

fields of the returned struct referring to unspecified parts of the message are filled strangely:



print_r(strptime('19841203', '%Y%m%d'));



Array

(

    [tm_sec] => 142611740

    [tm_min] => 12

    [tm_hour] => -1074490616

    [tm_mday] => 3

    [tm_mon] => 11

    [tm_year] => 84

    [tm_wday] => 1

    [tm_yday] => 337

    [unparsed] => 

)

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.

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.

//This turns non-standard but often used "datetime" string

//like '20060810084251' into nice formatted date

//'Thursday, 10 August 2006 08:42:51 CEST'

//note, that strptime returns day of year counting from 0, so

//you need to put 1 as month number to get appropriate

//month for the daycount. for 2006 strptime for unknown

//reason returns 106, so I simply add 1900



$informat = '%Y%m%d%H%M%S';

$outformat =  '%A, %d %B %Y %T %Z';

$ftime = strptime("20060810084251",$informat);

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().
