strptime — Parse a time/date generated with strftime()

Beschreibung

array strptime ( string $date , string $format )

strptime() returns an array with the date parsed, or FALSE on error.

Month and weekday names and other language dependent strings respect the current locale set with setlocale() (LC_TIME).

Parameter-Liste

date (string)

The string to parse (e.g. returned from strftime()).

format (string)

The format used in date (e.g. the same as used in strftime()). Note that some of the format options available to strftime() may not have any effect within strptime(); the exact subset that are supported will vary based on the operating system and C library in use.

For more information about the format options, read the strftime() page.

Rückgabewerte

Returns an arrayIm Fehlerfall wird FALSE zurückgegeben..

The following parameters are returned in the array
parameters Description
"tm_sec" Seconds after the minute (0-61)
"tm_min" Minutes after the hour (0-59)
"tm_hour" Hour since midnight (0-23)
"tm_mday" Day of the month (1-31)
"tm_mon" Months since January (0-11)
"tm_year" Years since 1900
"tm_wday" Days since Sunday (0-6)
"tm_yday" Days since January 1 (0-365)
"unparsed" the date part which was not recognized using the specified format

Beispiele

Beispiel #1 strptime() example

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

echo "$strf\n";

print_r(strptime($strf, $format));
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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] =>
)

Anmerkungen

Hinweis: Diese Funktion ist auf Windows-Plattformen nicht implementiert.

Hinweis:

Internally, this function calls the strptime() function provided by the system's C library. This function can exhibit noticeably different behaviour across different operating systems. The use of date_parse_from_format(), which does not suffer from these issues, is recommended on PHP 5.3.0 and later.

Hinweis:

"tm_sec" includes any leap seconds (currently upto 2 a year). For more information on leap seconds, see the » Wikipedia article on leap seconds.

Hinweis:

Prior to PHP 5.2.0, this function could return undefined behaviour. Notably, the "tm_sec", "tm_min" and "tm_hour" entries would return undefined values.

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

//'Thursday, 10 August 2006 08:42:51 CEST'
//note, that strptime returns day of year counting from 0, so

//reason returns 106, so I simply add 1900

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().
