Which means you've got to know what format any submitted date should be in, which means you've got to know which bits are day, month and year. > And no, I dont have to split the date up, the date() function should > be able to be used to validate the date. I asume it returns null, or > something sensable, if the date is invalid. date() won't do this, it's the function used to display a given timestamp in a human-readable format. Functions like mktime() accept apparently invalid values so as to allow for easy date arithmetic (date('d-M-Y', mktime(0, 0, 0, 1, 32, 2005)) will give you '01-Feb-2005', for example; strtotime() does something similar). The only built-in function that does the checking you are after is checkdate(), and that also wants day, month and year as three integers. So yes, you do have to split the input date up. > Anyway as the date format > is user defined I need both functions. No, you don't *need* them. You may prefer to have the function to decode according to a format string, but you don't need it -- it's pretty trivial to do the task without it. ( $aDate = explode('-', $inDate); // or preg_split("#[/.-]#", $inDate) if (checkdate($aDate[1], $aDate[0], $aDate[2])): $timestamp = mkdate(12, 0, 0, $aDate[1], $aDate[0], $aDate[2]); else: $timestamp = NULL; endif; ) > In this case it is a back end administration form as the (power) user > does not want to have to fiddle about with drop downs.

Well, but then you're splitting the date up into its constituent components anyway -- so what's all the fuss about??? Cheers!
