another reason to use shell_exec instead of system is when the result is multiple lines such as grep or ls <?php // this correctly sets answer string to all lines found //$answer = shell_exec ("grep 'set of color names' *.php "); //echo "answer = $answer"; // this passes all lines to output (they show on page) // and sets answer string to the final line $sys = system ("grep 'set of color names' *.php "); echo "sys =(($sys))"; ?> here is view/source resulting from system call setprefs.php:// The standard set of color names is: setprefs.php:// Most browsers accept a wider set of color names silly.php: //$answer = shell_exec ("grep 'set of color names' *.php "); silly.php: $sys = system ("grep 'set of color names' *.php "); sys =((silly.php: $sys = system ("grep 'set of color names' *.php ");)) and here is view source from using shell_exec instead answer = setprefs.php:// The standard set of color names is: setprefs.php:// Most browsers accept a wider set of color names silly.php: $answer = shell_exec ("grep 'set of color names' *.php "); silly.php:// $sys = system ("grep 'set of color names' *.php "); ---- Manual Page -- http://www.php.net/manual/en/function.system.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+35842 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+35842&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+35842&report=yes
