strptime

(PHP 5 >= 5.1.0)

strptime strftime() işleviyle üretilen zaman ve tarihleri çözümler

Açıklama

array strptime ( string $tarih , string $biçim )

strptime() işlevi çözümlenmiş tarih değiştirgesini bir diziyle döndürür. Hata durumlarındaysa FALSE değeriyle döner.

Ay, gün isimleri ve yerel ayarlarıyla ilgili dile bağımlı diğer dizgeler (LC_TIME), setlocale() işleviyle ayarlanır.

Değiştirgeler

tarih

Çözümlenen dizge (ör. strftime() işlevinden dönen değer)

biçim

tarih değiştirgesinde kullanılan biçim (ör. strftime() işlevinde kullanılanla aynı).

Biçimlendirme seçenekleri hakkında daha fazla bilgi için strftime() sayfasını okuyun.

Dönen Değerler

Dizi döndürür. Hata durumlarında FALSE değeriyle döner.

Diziyle dönen değerler
Değiştirge Açıklama
"tm_sec" Saniye (0-61)
"tm_min" Dakika (0-59)
"tm_hour" Saat (0-23)
"tm_mday" Gün (1-31)
"tm_mon" Ay (0-11)
"tm_year" 1900'den itibaren yıllar
"tm_wday" Pazar'dan itibaren hafta günleri (0-6)
"tm_yday" Ocak 1'den itibaren günler (0-365)
"unparsed" tarih değiştirgesinin bilinmeyen biçim değiştirgesi kullanımından dönen değer

Örnekler

Örnek 1 - strptime() örneği

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

echo 
"$strf\n";

print_r(strptime($strf$biçim));
?>

Yukarıdaki örnek şuna benzer bir çıktı üretir:

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] =>
)

Notlar

Bilginize: Bu işlev Windows sistemlerinde çalışmaz.

Bilginize:

"tm_sec" "artık saniyeleri" de içerir (yılda 2 saniyeye kadar). Artık saniyeler hakkında bilgi edinmek için » Wikipedia artık saniyeler makalesine bakınız.

Another portage for windows (from ex/yks toolkit)
<?php

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));

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.

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

preview :
<?php
/**
* Parse a time/date generated with strftime().
*
* This function is the same as the original one defined by PHP (Linux/Unix only),
*  but now you can use it on Windows too.
*  Limitation : Only this format can be parsed %S, %M, %H, %d, %m, %Y
*
* @author Lionel SAURON
* @version 1.0
* @public
*
* @param $sDate(string)    The string to parse (e.g. returned from strftime()).
* @param $sFormat(string)  The format used in date  (e.g. the same as used in strftime()).
* @return (array)          Returns an array with the <code>$sDate</code> parsed, or <code>false</code> on error.

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']);

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.

See http://dev.mysql.com/doc/refman/4.1/en/date-and-time-functions.html
