PS: I know it's not Friday, but this question came up in class yesterday and I thought maybe all of you might like to guess why null is Wednesday?

Wait.. What?? $ php -r 'echo date("l",NULL),"\n";' Wednesday Cos: $ php -r 'echo date("r",NULL),"\n";' Wed, 31 Dec 1969 18:00:00 -0600 (Personally, I would have thought Thursday should be NULL, but that's just me. And Thursday.)

Actually, It *is* Thursday if you use UTC: $ TZ=UTC php -r 'echo date("r",NULL),"\n";' Thu, 01 Jan 1970 00:00:00 +0000 :P

Perfect example of Tedd's last comment about being proven wrong (even though TECHNICALLY it isn't) Good job :)

To all: Okay, so now that we have had people reply, here's my take. The Unix timestamp started on 01 Jan 1970 00:00:00 +0000 -- and that was a Thursday. The second before (i.e., 31 December, 1969 23:59:59:59 + 0000) was null, which was Wednesday. Now one might argue that everything before was null and I could accept that. But here's my code and reasoning, please follow: $string = null;

$seconds = strtotime($string);    // change string into seconds
date = getdate($seconds);        // change seconds into a date
$computedDate = $date['mday'] . ' ' . $date['month'] . ', ' . $date['year'] . ' : ' .$date['weekday'];
echo($computedDate);    // show date

Thus, null is Wednesday. Now, why is this wrong? Cheers, tedd _____________________ tedd@sperling.com http://sperling.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
