The __wakeup() serialization magic method has been deprecated.¶

Description¶

Class serialization in PHP has had multiple mechanism introduced to control its behaviour by userland. Initially with the __sleep() and __wakeup() magic methods, then with the Serializable interface and finally with __serialize() and __unserialize().

In the end, the __serialize and __unserialize methods must be used, instead of __sleep and __wakeup.

Example¶

<?php

class X {
    function __sleep() {}
}

?>

Solutions¶

Rename the method to __unserialize.
