note 104852 added to function.checkdate

Many of the examples below display attempt to use checkdate to test a hand-entered date for validity. I don't think checkdate was meant for that. My experience has shown the following simple one liner to be the most effective: <?php $isvalid = strtotime($hand_entered_text) !== false; ?> I've created a test unit for this expression and thrown all sorts of weird stuff at it including dates with XML and found that it only returns true for anything that would fit exactly a date. The following would then be valid: 2011-07-11 15:27:41 2011-07-11 15:27:41 12/12/2001 December 31st, 2001 and these are not: 12/32/2001 random test null 0 56445 With some quick sub-string checks (for colons or slashes and dashes) you could very easily write a validator based on this that only accepts dates or times but not both. ---- Server IP: 69.147.83.197 Probable Submitter: 173.58.9.188 ---- Manual Page -- http://www.php.net/manual/en/function.checkdate.php Edit -- https://master.php.net/note/edit/104852 Del: integrated -- https://master.php.net/note/delete/104852/integrated Del: useless -- https://master.php.net/note/delete/104852/useless Del: bad code -- https://master.php.net/note/delete/104852/bad+code Del: spam -- https://master.php.net/note/delete/104852/spam Del: non-english -- https://master.php.net/note/delete/104852/non-english Del: in docs -- https://master.php.net/note/delete/104852/in+docs Del: other reasons-- https://master.php.net/note/delete/104852 Reject -- https://master.php.net/note/reject/104852 Search -- https://master.php.net/manage/user-notes.php
