Phasing out Serializable interface
The Serializable mechanism has issues:
temperature);
}
public function unserialize($payload) {
$this->temperature = unserialize($payload);
}
}]]>
State is required between nested calls with %parent::serialize%
There is no requirement for what *is* used in %serialize%/%unserialize%
PHP 7.4 introduced a new serializing mechanism through magic methods, with a stricter set of guarantees:
$this->temperature];
}
public function __unserialize(array $data) {
$this->temperature = $data['t'];
}
}]]>
PHP 8.1 starts the removal process of "only %Serializable%" classes:
In PHP 8.1, implementing %Serializable% will throw a deprecation warning
In PHP 9.0, the %Serializable% interface will be removed, and %unserialize% will stop understanding its serialisation format
