the code below was talking of function declarations ... reffer to the thread.
will code injection in case of function declarations work? I am not sure!!

;)

<?php
function add($a,$b,$c){
return $a+$b+$c ;
}
echo add(2,null,3);
# even if you pass the value of $b in the url as a get or post
param... it wont work.
?>

thanks,
vedanta
