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);

/*Returns:
array(12) {
    ["year"]=> int(2010)
    ["month"]=> int(2)
    ["day"]=> int(1)    //<---expected false like below
    ["hour"]=> bool(false)
    ["minute"]=> bool(false)
    ["second"]=> bool(false)
    ["fraction"]=> bool(false)
    ["warning_count"]=> int(0)
    ["warnings"]=> array(0) { }
    ["error_count"]=> int(0)
    ["errors"]=> array(0) { }
    ["is_localtime"]=> bool(false)
}*/

<?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.

Careful - date_parse is perfectly happy with something like this:

 date_parse("2006-2-31");
