var_dump($wrapper->getObject());

$wrapper = unserialize(serialize($wrapper));

var_dump($wrapper->getObject());

Output for git.master, git.master_jit, rfc.property-hooks: Deprecated: WrapperObject 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/0FP1F on line 14 object(ObjectWithReferences)#2 (2) { ["var1":protected]=> object(stdClass)#3 (0) { } ["var2":protected]=> object(stdClass)#3 (0) { } } object(ObjectWithReferences)#6 (2) { ["var1":protected]=> object(stdClass)#7 (0) { } ["var2":protected]=> *RECURSION* }
