note 69930 added to function.exec

Note that on Linux/UNIX/etc, both the command and any parameters you send is visible to anyone with access to ps. For example, take some php code that calls an external program, and sends a sort of password as a parameter. <?php exec("/usr/bin/secureprogram password"); ?> The entire string (actually probably something like "secureprogram password") will be visible to any user that executes ps -A -F. If you are going to be doing a lot of external calling, or any of it needs to be somewhat secure, you are probably better off writing a php extension. ---- Server IP: 66.207.199.35 Probable Submitter: 141.213.221.165 ---- Manual Page -- http://www.php.net/manual/en/function.exec.php Edit -- https://master.php.net/note/edit/69930 Del: integrated -- https://master.php.net/note/delete/69930/integrated Del: useless -- https://master.php.net/note/delete/69930/useless Del: bad code -- https://master.php.net/note/delete/69930/bad+code Del: spam -- https://master.php.net/note/delete/69930/spam Del: non-english -- https://master.php.net/note/delete/69930/non-english Del: in docs -- https://master.php.net/note/delete/69930/in+docs Del: other reasons-- https://master.php.net/note/delete/69930 Reject -- https://master.php.net/note/reject/69930 Search -- https://master.php.net/manage/user-notes.php
