Subtract By OperatorSubtracts a variable by the right hand value (expression)
The Subtract By operator takes the value of the variable specified on the left side of the operator and subtracts it by 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.
» $i = 3
» $i -= 2
» $i
1
Unlike with the standard arithmetic operators (+
,
-
, *
, /
), silent data casting
isn’t supported with arithmetic assignments like +=
,
-=
, *=
and /=
. Not even when

You can work around this by using the slightly longer syntax: variable = value op value, for example:
» $i = "3"
» $i = $i + "2"
» $i
