Here is an example that might help.
$a = 1;
if($a)
echo '1';
if($a == true)
echo '2';
if($a === true)
echo '3';
The first and second conditional statements execute but the third doesn't.
This is because $a evaluates to true but is not of type 'boolean'. === and
!== not only compare value but type as well.
