Note Submitter: petruzanauticoyahoo?com!ar ---- I've come up with a little not-so-clean but useful function to avoid checking if a variable is set before reading its value, specially useful for $_REQUEST and the like: <?php function toLocal( $source, &$dest, $default = null ) { if( isset( $source ) ) $dest = $source; else $dest = $default; } ?> and then call it this way: <?php @toLocal( $_REQUEST['item_id'], $item_id, 0 ); ?> It checks wether the variable is set, copies it to a local variable, and if it wasn't set, it assigns the new variable a default value, all in one line, preventing you to have to always check for isset() before trying to read its value. Gotta call it with @ because if the variable is not set, then trying to pass it as an argument will yield a warning. Petruza.
