Output for git.master, git.master_jit, rfc.property-hooks: Deprecated: Foo 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/64GT7 on line 7 Deprecated: Bar 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/64GT7 on line 24 object(Bar)#4 (2) { ["var1":"Foo":private]=> array(1) { [0]=> object(Role)#6 (0) { } } ["var2":"Bar":private]=> object(stdClass)#5 (0) { } }
