extract() and symbol tables...

Before I ask the real question, a lead-in: Is a separate symbol table created for user-defined functions? Now, the real question: When running extract() inside a user-defined function, are the variables imported into the global symbol table, or to a symbol table local to the function, assuming the answer to Q1 was yes? Ta, a d a m _______________________________________________________ <?php $s=array("&#74;","&#65;","&#112;","&#104;","&#112;","&#72;"); for($i=0;$i<count($s);$i++){echo$s[$i];} ?> :)
