note 77674 added to function.move-uploaded-file

So yet another (though I believe simpler and more fool proof) way of ensuring the file uploaded has a unique name is to use a for loop to test the existence of the file, and increment the n value to append to the file name. As for the issue of ensuring n comes before the file extension, I suggest using strrpos to find the position of the last dot, which presumably should come before the extension, and then use 2 instances of substr to split it up. $savefile= $uploaddir . basename($_FILES['userfile']['name']); $uploadfile = $savefile; //duplicate variable so that appending numbers doesn't result in sequences like 0 01 012 and so forth. for($n=0;file_exists($uploadfile);$n++) { $dotPos = strrpos($savefile,"."); $savefile = substr($savefile,0,$dotPos).$n.substr($savefile,$dotPos); } ---- Server IP: 64.71.164.2 Probable Submitter: 63.164.145.198 ---- Manual Page -- http://www.php.net/manual/en/function.move-uploaded-file.php Edit -- https://master.php.net/note/edit/77674 Del: integrated -- https://master.php.net/note/delete/77674/integrated Del: useless -- https://master.php.net/note/delete/77674/useless Del: bad code -- https://master.php.net/note/delete/77674/bad+code Del: spam -- https://master.php.net/note/delete/77674/spam Del: non-english -- https://master.php.net/note/delete/77674/non-english Del: in docs -- https://master.php.net/note/delete/77674/in+docs Del: other reasons-- https://master.php.net/note/delete/77674 Reject -- https://master.php.net/note/reject/77674 Search -- https://master.php.net/manage/user-notes.php
