note 89582 added to function.readdir

This function is used to display random image i.e. at header position of a site. It reads the whole directory and then randomly print the image. I think it may be useful for someone. <?php if ($handle = opendir('images/')) { $dir_array = array(); while (false !== ($file = readdir($handle))) { if($file!="." && $file!=".."){ $dir_array[] = $file; } } echo $dir_array[rand(0,count($dir_array))]; closedir($handle); } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 119.153.37.79 ---- Manual Page -- http://www.php.net/manual/en/function.readdir.php Edit -- https://master.php.net/note/edit/89582 Del: integrated -- https://master.php.net/note/delete/89582/integrated Del: useless -- https://master.php.net/note/delete/89582/useless Del: bad code -- https://master.php.net/note/delete/89582/bad+code Del: spam -- https://master.php.net/note/delete/89582/spam Del: non-english -- https://master.php.net/note/delete/89582/non-english Del: in docs -- https://master.php.net/note/delete/89582/in+docs Del: other reasons-- https://master.php.net/note/delete/89582 Reject -- https://master.php.net/note/reject/89582 Search -- https://master.php.net/manage/user-notes.php
