Deprecated: Symfony\Component\VarExporter\Tests\Fixtures\MySerializable implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary) in /home/pataplou/www/patrick/pataplouf/vendor/symfony/var-exporter/Tests/Fixtures/MySerializable.php on line 14
