PHP Operators: The === Operator

PHP Operators: The === Operator

Posted by at 2:17 am

PHP’s === Operator enables you to compare or test variables for both equality and type. Refer below for example.

<?php
//define variables..
$str = '9';
$int = 9;

//Returns true since both variable contains the same value..
$res = ($str==$int);

//Returns false since the two variables are not of the same type..
$res = ($str===$int);
?>

    That’s actualy a pretty useful operator. You’d think that there’s not much you can do with that but in reality it has so many uses you wouldn’t belive it…

    I usually use the double equal sign == to test equality and never used this triple equal. Maybe because there’s no situation that requires it but thank you for pointing this one.

    I always get lost when it comes to those “=” “==” “===” operators. Had no idea there even was a “===” one.
