If you're using PHP4 and need similar usage of this function there is getdate() however, getdate() only accepts a timestamp and not a date time; a work around is to use strtotime() in conjunction.
Example usage:
getdate(strtotime('2006-12-12 10:00:00'));
Result:
Array
(
[seconds] => 0
[minutes] => 0
[hours] => 10
[mday] => 12
[wday] => 2
[mon] => 12
[year] => 2006
[yday] => 345
[weekday] => Tuesday
[month] => December
[0] => 1165946400
)
Note: This is only helpful if you're looking just for the month, day, year, hour, minute, second values.
