Output for git.master, git.master_jit, rfc.property-hooks: Deprecated: a 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/g3T71 on line 4 array(1) { [0]=> array(2) { ["field1"]=> object(a)#3 (2) { ["b":"a":private]=> object(b)#2 (1) { ["b":"b":private]=> string(4) "test" } ["v":"a":private]=> int(1) } ["field2"]=> object(a)#4 (2) { ["b":"a":private]=> object(b)#2 (1) { ["b":"b":private]=> string(4) "test" } ["v":"a":private]=> int(2) } } } bool(true)
