Re: No is_date() function?

There is no such a thing as a date datatype in PHP. Dates are stored as an integer representing seconds since a base time (1/1/1970) and they cannot be distinguished from other integers. In PHP 5.1 they added a DateTime class which is a good thing for the future, to solve issues like yours, but for the time being, a 'timestamp' as returned by, for example' mktime, is a plain integer.

Hi I wrote a serialization function to turn arbitrary PHP variables into Macintosh plist compatible XML but see that there is no "is_date" tester as there is for bool, object, array etc. Is there a relatively simple (and robust) way to detect if a variable is a date? For example: $person = array('name'=>'bob', 'sex'=>'male', 'date_of_birth'=> $someDateHere); Thanks for any help Ken -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- No virus found in this incoming message.
