*= Multiply By Operator

Multiplies a variable by the right hand value (expression)

Description

The Multiply By operator takes the value of the variable specified on the left side of the operator and multiplies it with the value on the right hand side Then it assigns the result back to the variable specified on the left side.

It is ostensibly just shorthand for $i = $i * value.

This operator is only available in expressions.

Examples

» $i = 3
» $i *= 2
» $i
5

Detail

Strict Types

Unlike with the standard arithmetic operators (+, -, *, /), silent data casting isn't supported with arithmetic assignments like +=, -=, *= and /=. Not even when strict-types is disabled (read more)

You can work around this by using the slightly longer syntax: variable = value op value, for example:

» $i = "3"
» $i = $i + "2"
» $i
5
