note 79954 added to function.file-exists

Very simple solution for a remote version of file_exists when checking to see if image URL exists This uses the getimagesize() function that attempts to read the width, height and other attributes for an image. My thought process was that if it returns a width, the image must exist... if not, replace it with a default or do whatever you want with it // can't find image, use a default thumbnail instead if(!$size=@getimagesize(protecturl($URL_OF_IMAGE))){ $replacementimageurl="images/defaultthumb.gif"; // same as return FALSE; } This sort of thinking can be applied to other file types using pre-existing functions. ---- Server IP: 66.207.199.35 Probable Submitter: 210.84.50.46 ---- Manual Page -- http://www.php.net/manual/en/function.file-exists.php Edit -- https://master.php.net/note/edit/79954 Del: integrated -- https://master.php.net/note/delete/79954/integrated Del: useless -- https://master.php.net/note/delete/79954/useless Del: bad code -- https://master.php.net/note/delete/79954/bad+code Del: spam -- https://master.php.net/note/delete/79954/spam Del: non-english -- https://master.php.net/note/delete/79954/non-english Del: in docs -- https://master.php.net/note/delete/79954/in+docs Del: other reasons-- https://master.php.net/note/delete/79954 Reject -- https://master.php.net/note/reject/79954 Search -- https://master.php.net/manage/user-notes.php
