note 107510 added to function.checkdate

This is a very good function to check if a date format is valid (with regex). For example: 2012-2-28 = Valid 2012-2-29 = Valid (leap year) 2012-2-30 = Invalid 2012-1-30 = Valid 2012-1-31 = Valid 2012-2-32 = Invalid Ensure there are no spaces in the preg_match function: <?php function Valid_Date_Format($date) { $converted=str_replace('/','-',$date); if(preg_match("/^((((19|20)(([02468][048])|([13579][26]))-02-29))|((20[0-9][0-9])|(19[0-9][0-9]))-((((0[1-9])| (1[0-2]))-((0[1-9])|(1\d)|(2[0-8])))|((((0[13578])|(1[02]))-31)|(((0[1,3-9])| (1[0-2]))-(29|30)))))$/",$converted)===1) { return TRUE; } return FALSE; } ?> I don't know where I got the original code from but I've not found anything better. ---- Server IP: 92.48.74.199 Probable Submitter: 81.136.202.145 ---- Manual Page -- http://www.php.net/manual/en/function.checkdate.php Edit -- https://master.php.net/note/edit/107510 Del: integrated -- https://master.php.net/note/delete/107510/integrated Del: useless -- https://master.php.net/note/delete/107510/useless Del: bad code -- https://master.php.net/note/delete/107510/bad+code Del: spam -- https://master.php.net/note/delete/107510/spam Del: non-english -- https://master.php.net/note/delete/107510/non-english Del: in docs -- https://master.php.net/note/delete/107510/in+docs Del: other reasons-- https://master.php.net/note/delete/107510 Reject -- https://master.php.net/note/reject/107510 Search -- https://master.php.net/manage/user-notes.php
