note 89517 added to function.opendir

The easiest way to get a dir listing and sort it is to exec() out to ls (eg:'ls -t'). But, that is considered "unsafe". My hosting company finally caught me doing it so here is my fastest solution. (Lucky for me each file is created with a Unix Timestamp at the end of the name and no other numbers in it.) <?php #exec('ls -t ./images/motion_detection/', $files); # They outlawed exec, so now I have to do it by hand. if ($handle = opendir('./images/motion_detection/')) { $files=array(); while (false !== ($file = readdir($handle))) { $files[$file] = preg_replace('/[^0-9]/', '', $file); # Timestamps may not be unique, file names are. } closedir($handle); arsort($files); $files=array_keys($files); } ?> Before you go copying someone's bloat kitchen sink function/class, consider what you have and what you really need. ---- Server IP: 64.71.164.2 Probable Submitter: 76.20.201.249 ---- Manual Page -- http://www.php.net/manual/en/function.opendir.php Edit -- https://master.php.net/note/edit/89517 Del: integrated -- https://master.php.net/note/delete/89517/integrated Del: useless -- https://master.php.net/note/delete/89517/useless Del: bad code -- https://master.php.net/note/delete/89517/bad+code Del: spam -- https://master.php.net/note/delete/89517/spam Del: non-english -- https://master.php.net/note/delete/89517/non-english Del: in docs -- https://master.php.net/note/delete/89517/in+docs Del: other reasons-- https://master.php.net/note/delete/89517 Reject -- https://master.php.net/note/reject/89517 Search -- https://master.php.net/manage/user-notes.php
