If you want to swap values between variables without using an intermediary, try using the list() and
array() language constructs. For instance:
<?
// Initial values.
$biggest = 1;
$smallest = 10;
// Instead of using a temporary variable...
$temp = $biggest;
$biggest = $smallest;
$smallest = $temp;
// ...Just swap the values.
list($biggest, $smallest) = array($smallest, $biggest);
?>
This works with any number of variables; you're not limited to just swapping two.
Cheers,
