说明
$date
)参数
-
date -
Date in format accepted by strtotime() .
返回值
Returns array with information about the parsed date
on success 或者在失败时返回 FALSE .
错误／异常
In case the date format has an error, the element 'errors' will contains the error messages.
范例
Example #1 A date_parse() example
<?php
print_r ( date_parse ( "2006-12-12 10:00:00.5" ));
?> 以上例程会输出：
Array
(
[year] => 2006
[month] => 12
[day] => 12
[hour] => 10
[minute] => 0
[second] => 0
[fraction] => 0.5
[warning_count] => 0
[warnings] => Array()
[error_count] => 0
[errors] => Array()
[is_localtime] =>
)
Relative formats do not influence the values parsed from absolute formats, but are parsed into the "relative" element.
Example #2 date_parse() with relative formats
<?php
print_r ( date_parse ( "2006-12-12 10:00:00.5 +1 week +1 hour" ));
?> 以上例程会输出：
Array
(
[year] => 2006
[month] => 12
[day] => 12
[hour] => 10
[minute] => 0
[second] => 0
[fraction] => 0.5
[warning_count] => 0
[warnings] => Array
(
) [error_count] => 0
[errors] => Array
(
) [is_localtime] =>
[relative] => Array
(
[year] => 0
[month] => 0
[day] => 7
[hour] => 1
[minute] => 0
[second] => 0

Here is a workaround for the "Feb 2010" problem. It also handles "2014".

A warning to some
<?php
$time = "00:14:38"
$parse_date = date_parse($time);
echo var_dump($parse_date) ."<br>";
//here you will get what you expect
$time = "-00:14:38"
$parse_date = date_parse($time);
echo var_dump($parse_date) ."<br>";
//here you will recieve hours minutes and seconds as booleans and as false and you will get error set to "Unexpected character"
$time = "00:-14:38"
$parse_date = date_parse($time);
echo var_dump($parse_date) ."<br>";
//here you will recieve the same as the above
$time = "00:14:-38"
$parse_date = date_parse($time);
echo var_dump($parse_date) ."<br>";
//here you will receive hours as 00 minutes as 14 and seconds as 0. The error will get set as the same as above. Meaning "Unexpected character"

See checkdate() at http://php.net/manual/en/function.checkdate.php for Gregorian date validation.

Be aware that date_parse() is happy with just a time zone and it can be pretty counter-intuitive. E.g.:
<?php
var_dump( date_parse('Europe/Madrid') );
?>
... prints an array where year, month, day... are FALSE. But so do these:
<?php
var_dump( date_parse('A') );
var_dump( date_parse('B') );
var_dump( date_parse('X') );
?>
Don't forget to further validate date_parse()'s output even when it isn't FALSE and the 'errors' key is empty.

A warning to others. Some keys will return with a default value where others will return as false if the date string has it omitted. Unsure if this is a bug or feature, but hopefully this will save someone some time.
<?php
///Example
$input = "Feb 2010";
$info = date_parse($input);
var_dump($info);
?>

<?php
$ida = '091122671325';
$idb = '091123671325';
// This function will match the identity number up to the day, but only for a maximum of 99years+364days.
// Will not work when checking persons older than 100years-1day.
function idtodate($id)
{
$year = date("Y");
$month = date("m");
$day = date("d");
$nc = substr($year, 0, 2);
$ny = substr($year, 2, 2);
$y = substr($id, 0, 2);
$m = substr($id, 2, 2);
$d = substr($id, 4, 2);
if($y.$m.$d <= $ny.$month.$day-1) {
$newc = $nc;
} else {
$newc = $nc-1;
}
$new = $newc.$y;
return array('year' => $new, 'month' => $m, 'day' => $d);
}
echo 'ID: '.$ida.'<br>';
print_r(idtodate($ida));
echo '<br><br>';
echo 'ID: '.$idb.'<br>';
print_r(idtodate($idb));
?>
Output:
1. If the year-month-day is smaller than today (2009-11-23), but bigger than 1999: year => 2009
ID: 091122671325
Array ( [year] => 2009 [month] => 11 [day] => 22 )
2. If the year-month-day is the same as, or bigger than today, but smaller than 2000: year => 1909
ID: 091123671325
Array ( [year] => 1909 [month] => 11 [day] => 23 )

Caution: date_parse expects months 1..12 only.
date_parse("13/1/5769") for month=13, Ehul in Jewish calendar, results in month==3 instead of month==13.
It does, however, report the error array showing "Unexpected Character."
It would be nice if date_parse could handle the months properly (just report back a "13" for the month). The older approach of substr() is my workaround.
[#8] gpayne at galenaparkisd com [2007-09-29 16:52:42]
Careful - date_parse is perfectly happy with something like this:
date_parse("2006-2-31");
