Output for git.master, git.master_jit, rfc.property-hooks: Deprecated: Widget 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/NQg0W on line 2 array(4) { [0]=> object(Widget)#7 (1) { ["references"]=> array(1) { [0]=> object(Placeholder)#8 (1) { ["id"]=> int(1) } } } [1]=> object(Widget)#9 (1) { ["references"]=> array(1) { [0]=> object(Placeholder)#10 (1) { ["id"]=> int(2) } } } [2]=> object(Widget)#11 (1) { ["references"]=> array(1) { [0]=> object(Placeholder)#8 (1) { ["id"]=> int(1) } } } [3]=> object(Widget)#12 (1) { ["references"]=> array(1) { [0]=> object(Placeholder)#8 (1) { ["id"]=> int(1) } } } }
