The expression
$magic_quotes of type false|integer is loosely compared to true ; this is ambiguous if the integer can be 0. You might want to explicitly use !== false instead.
In PHP, under loose comparison (like For 0 == false // true
0 == null // true
123 == false // false
123 == null // false
// It is often better to use strict comparison
0 === false // false
0 === null // false
