PHP Type Casting.

Type casting can cause a variable's value to be treated as a specific type.

Syntax:

variableName1 = (newType) variableName2;

Example:-

<?php
       $a = 5.5;
       echo $a;             // Displays "5.5"
       echo (string)$a;     // Displays "5.5"
       echo (int) $a;       // Displays "5"
       echo (float) $a;     // Displays "5.5"
       echo (boolean) $a;   // Displays "1"  
?>
