note 23790 added to function.system

Assuming that 0 = false and 1 = true doesn't always work. If you are having problems trying to figure out why the system() function sometimes seems to return true/false backwards, you should verify the return codes of the system command you are executing. For example: <? $cmd="/usr/bin/mysql -h$host -u$user -p$pass -e'$command'"; $res = (system($cmd)) ? true : false; print $res; ?> // if the command fails, 1 will be printed. // if the command works, 0 will be printed. <? if(system($cmd) === false) { print "Failed"; } else { print "Success"; } ?> // outputs Success when it fails This is due to mysql returning 0 if no errors have occurred and returning 1 if errors have occurred. Might be good to look up returned error codes of the system command you are executing to make sure you are branching correctly. -- http://www.php.net/manual/en/function.system.php http://master.php.net/manage/user-notes.php?action=edit+23790 http://master.php.net/manage/user-notes.php?action=delete+23790 http://master.php.net/manage/user-notes.php?action=reject+23790
