note 103769 added to function.readdir

Looking through the examples, I can't see any that do a simple check on the value of the directory resource that opendir returns and is subsequently used by readdir. If opendir returns false, and you simply pass this to the readdir call in the while loop, you will get an infinite loop. A simple test helps prevent this: <?php $dir = opendir($path); while ($dir && ($file = readdir($path)) !== false) { // do stuff } ?> ---- Server IP: 117.104.162.229 Probable Submitter: 203.122.234.143 (proxied: 203.122.234.143) ---- Manual Page -- http://www.php.net/manual/en/function.readdir.php Edit -- https://master.php.net/note/edit/103769 Del: integrated -- https://master.php.net/note/delete/103769/integrated Del: useless -- https://master.php.net/note/delete/103769/useless Del: bad code -- https://master.php.net/note/delete/103769/bad+code Del: spam -- https://master.php.net/note/delete/103769/spam Del: non-english -- https://master.php.net/note/delete/103769/non-english Del: in docs -- https://master.php.net/note/delete/103769/in+docs Del: other reasons-- https://master.php.net/note/delete/103769 Reject -- https://master.php.net/note/reject/103769 Search -- https://master.php.net/manage/user-notes.php
