Link: http://git.php.net/?p=php-src.git;a=commitdiff;h=cfd104582220d578ab1b78a5991065d038e1f931 Log: Add optional second arg to unserialize() Returns the number of bytes consumed by reference for streaming unserialization. Actual unserialization behavior is not modified at all. The need for this came up while trying to parse SplDoublyLinkedList's serialization format which uses a non-standard stream of serialized values.
