note 65627 added to function.shell-exec

Each time you call shell_exec, it operates in a completely new shell. So if you need to do different multiple things in it based on whatever criteria, assemble your command ahead of time: instead of <?php shell_exec("cd $path_to_dir"); shell_exec("ls -l"); ?> which, as you noted, won't work, do <?php $cmd = "cd $path_to_dir; "; if($a == true)$cmd .= "ls -l"; else $cmd .= "du -h"; $result = shell_exec($cmd); ?> ---- Server IP: 64.71.164.2 Probable Submitter: 66.188.26.156 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.shell-exec.php Edit -- http://master.php.net/note/edit/65627 Del: integrated -- http://master.php.net/note/delete/65627/integrated Del: useless -- http://master.php.net/note/delete/65627/useless Del: bad code -- http://master.php.net/note/delete/65627/bad+code Del: spam -- http://master.php.net/note/delete/65627/spam Del: non-english -- http://master.php.net/note/delete/65627/non-english Del: in docs -- http://master.php.net/note/delete/65627/in+docs Del: other reasons-- http://master.php.net/note/delete/65627 Reject -- http://master.php.net/note/reject/65627 Search -- http://master.php.net/manage/user-notes.php
