It's a strong test of equality. Unlike == which tests if two values are the same, === also tests whether the types being compared are the same.

Hence, a statement such as

will evaluate true if $var = 1, whereas

will evaluate false if $var = 1

$a === $b Identical TRUE if $a is equal to $b, and they are of the same type. (introduced in PHP 4)
