ok - finally had to come up with my own regexp - and am failing. Trying to validate an input of a time value in the format hh:mm, wherein I'll accept anything like the following: hmm hhmm h:mm hh:mm in a 12 hour format. My problem is my test is ok'ing an input of 1300. Here is my test: if (0 == preg_match("/([0][1-9]|[1][0-2]|[1-9]):[0-5][0-9]/",$t)) return true; else return false; Can someone help me correct my regexp? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
