Let?s assume that you have the following
foreachstatement:$itemValueis assigned by reference. This is possible because the expression (in the example$array) can be used as a reference target.However, if we were to replace
$arraywith something different like the result of a function call as inthen assigning by reference is not possible anymore as there is no target that could be modified.
Available Fixes
1. Do not assign by reference
2. Assign to a local variable first
3. Return a reference
