Deprecated: T 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/WDj2Z on line 3 array(1) { ["_data"]=> array(4) { ["a"]=> int(1) ["b"]=> int(2) ["c"]=> int(3) ["d"]=> array(3) { [0]=> string(1) "x" [1]=> string(1) "y" [2]=> string(1) "z" } } } array(1) { ["_data"]=> array(4) { ["a"]=> int(1) ["b"]=> int(2) ["c"]=> int(3) ["d"]=> string(42) "a:3:{i:0;s:1:"x";i:1;s:1:"y";i:2;s:1:"z";}" } } string(132) "C:1:"T":118:{a:1:{s:5:"_data";a:4:{s:1:"a";i:1;s:1:"b";i:2;s:1:"c";i:3;s:1:"d";s:42:"a:3:{i:0;s:1:"x";i:1;s:1:"y";i:2;s:1:"z";}";}}}"
