Add With Operator
Adds the right hand value to a variable (expression)
Description
The Add With operator takes the value of the variable specified on the left side of the operator and adds 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
