PHP Operator ===

PHP’s === Operator enables you to compare or test variables for both equality and type. Refer below for example. [code] <?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); ?> [/code]
