[PHP] How to apply something to every variable

[Chris Anderson]

I was playing around trying to find a way to addslashes() to all my variables, and I 
came up with this snippet. Hope it helps someone

 $keys = array_keys($HTTP_POST_VARS);
 $post_size = sizeof($keys);
 for($x = 0; $x < $post_size; $x++)
 {
  $temp = $keys[$x];
//you can replace addslashes with whatever you want to use
  ${"$temp"} = addslashes($HTTP_POST_VARS["$temp"]);
 }
