Expected result AFTER applying this Pull Request

no more deprecation

@PhilETaylor public function __serialize(): array ... shouldn't that be public function __serialize(): string?

[richard67]

serialize() checks if the class has a function with the magic name __serialize(). If so, that function is executed prior to any serialization. It must construct and return an associative array of key/value pairs that represent the serialized form of the object. If no array is returned a TypeError will be thrown.

Gulp. I am confused.

[richard67]

Surely this is missing the actual implementation of the these functions?

@PhilETaylor It should be enough if they call the serialize() and unserialize($serialized) methods defined a bit above, right? Or can they even be aliased somehow?
