Responding to: johan dot mickelin at gmail dot com 31-May-2007 07:52 ------------------------------------------------------- If you want to list only a certain filetype, this case only jpg and gif files in an image directory $dir = opendir ("../images"); while (false !== ($file = readdir($dir))) { if (strpos($file, '.gif',1)||strpos($file, '.jpg',1) ) { echo "$file <br />"; } } ----------------------------------------------------------------- This function would also echo files that have .gif or .jpg in their names such as myFile.gif.php (I don't know why I'd name a file like that, but I am just making a point, that's all folks!) Perhaps a more exact way is to do the following: ... while (false !== ($file = readdir($dir))) { $lenOfFileName = strlen($file); $extOffsetPos = $lenOfFileName - 5; if (strpos($file, '.gif', $extOffsetPos) || strpos($file, '.jpg',$extOffsetPos) ) { echo "$file <br />"; } ... If your extensions are more than three letters, then increase the 5 to 6 (e.g. aspx) to 7 (e.g. php51) or whatever. ---- Server IP: 69.147.83.197 Probable Submitter: 196.205.206.106 ---- Manual Page -- http://www.php.net/manual/en/function.readdir.php Edit -- https://master.php.net/note/edit/76377 Del: integrated -- https://master.php.net/note/delete/76377/integrated Del: useless -- https://master.php.net/note/delete/76377/useless Del: bad code -- https://master.php.net/note/delete/76377/bad+code Del: spam -- https://master.php.net/note/delete/76377/spam Del: non-english -- https://master.php.net/note/delete/76377/non-english Del: in docs -- https://master.php.net/note/delete/76377/in+docs Del: other reasons-- https://master.php.net/note/delete/76377 Reject -- https://master.php.net/note/reject/76377 Search -- https://master.php.net/manage/user-notes.php
