The operator ==
only checks that left and right values are equal. The operator ===
, checks if left and right values are equal, and also checks to see if they are of the same variable type.
$a == $b Igual TRUE se $a é igual a $b.
$a === $b Idêntico TRUE se $a é igual a $b, e eles são do mesmo tipo. (introduced in PHP 4)
