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

Description

array strptime ( string date, string format )

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

Примеры

Пример 1. strptime() example

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

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().

Note that elements that are not found (since they don't exist in the specified format) will NOT be set to null.

Also a two-digit-year (found with %y) is returned as 1969-2068 (or 69-168 since this function returns years since 1900).

<?php
$format = '%y-%m-%d';
$testdate = '69-04-03';
$founddate = strptime ($testdate, $format);
var_dump ($founddate);
?>

returns

array(9) {
  ["tm_sec"]=>
  int(-1212975008)
  ["tm_min"]=>
  int(28)
  ["tm_hour"]=>
  int(140)
  ["tm_mday"]=>
  int(3)
  ["tm_mon"]=>
  int(3)
  ["tm_year"]=>
  int(69)
  ["tm_wday"]=>
  int(4)
  ["tm_yday"]=>
  int(92)
  ["unparsed"]=>
  string(0) ""
}
