Output for git.master, git.master_jit, rfc.property-hooks: Deprecated: SerializableClass implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary) in /in/cZqVf on line 3 array(2) { ["obj1"]=> object(SerializableClass)#5 (1) { ["sharedProp"]=> object(stdClass)#6 (1) { ["name"]=> string(4) "test" } } ["obj2"]=> object(SerializableClass)#7 (1) { ["sharedProp"]=> object(stdClass)#8 (1) { ["name"]=> string(4) "test" } } }
