Back in the day, I worked on a project that used our own variation of this type of functionality. We had this function that helped a little function alternate(&$a, $b) { return $a = ( $a ? $a : $b ); } function query($sql, $params=array()) { alternate($params, array()); extract($params); alternate($parameters, null); alternate($showSQL, false); alternate($showErrors, true); alternate($execute, true); alternate($noHTML, false); alternate($profile, 0); # Do your thing... } This allowed for us to include/exclude whatever we wanted from the it is a little long winded to get to what you are looking for ( I think ) But it worked for us. -- Jim Lucas "Some men are born to greatness, some achieve greatness, and some have greatness thrust upon them."
