If you don't understand this, please read this page: http://www.php.net/manual/en/function.pcntl-fork.php
2 You must use == in your if condition.
Look at the first example on the above page.
3 ??? Why do you have a function defined in your else clause???
The only reason I can think of would be to isolate the inside code from the work. But, this could also lead to the missing variable issue the OP is asking about.
