    From http://us.php.net/manual/en/language.operators.comparison.php

    $a == $b    Equal   TRUE if $a is equal to $b after type juggling.
$a === $b   Identical   TRUE if $a is equal to $b, and they are of the same type.
$a != $b    Not equal   TRUE if $a is not equal to $b after type juggling.
$a <> $b    Not equal   TRUE if $a is not equal to $b after type juggling.
$a !== $b   Not identical   TRUE if $a is not equal to $b, or they are not of the same type.
