PHP : Function Reference : Date and Time Functions : strptime

strptime

Parse a time/date generated with strftime (PHP 5 >= 5.1.0)
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).

Note:

This function is not implemented on Windows platforms.

Parameters

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()).

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

Return Values

Returns an array, or FALSE on failure.

Table 45. 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


Examples

Example 462. strptime() example

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

echo "$strf\n";

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

The above example will output something similar to:

   [tm_sec] => 19

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().

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

//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);

                   $ftime['tm_yday'] + 1,
                  $ftime['tm_year'] + 1900
                );
//setlocale(LC_TIME,'pl_PL');
echo strftime($outformat , $unxTimestamp );
