Multiplication

Multiplication is the mathematical multiplication. It applies to numbers: integers and float.

It also works with booleans and null, which are first converted to integers. Other types are not allowed for multiplication and yield a fatal error.

The operator for multiplication is the star *. A double star ** is the power operator. The opposite operation is the division \.

<?php

    $a = 10 * 2.3; // 23.0
    $b = 0.5 * 2;  // 1

?>
