Hello, That is correct, the manual says "The [assignement] syntax can be used with functions, that return references". So the function should return reference to be assigned properly by reference to a variable. Nevertheless it could be intersting to warn about that change of behavior which occurse on version 5.0.5. Because no PHP Error message neither Notice are prompted when the function doesn't return references.
