as you can see i call the finish() function at the bottom. the finish function calls the debug('close') function. look at that and it's comment.

if you looked at the comment., i cnA'T FIND OUT WHY THAT VARIABLE IS EMPTY.

thanks in advance this

if($this->debug_on == false){

will not be true, ever. when you set something to true or false it is really being turned to 1 or 0, not false or true. they will be boolean, not a stringcouldn't you do this though?
if($this->debug_on === false){damn just when you think you're getting good at it thanksOriginally posted by Josh

if($this->debug_on === false){
yesm tha tis the proper way to do it. so eiher way is fine. just not ==
