I noticed that strange behaviour during actual usage of SplObjectStorage with really deep objects. Using __debugInfo() to print only object ids is a bless. ------------------------------------------------------------------------ [2015-03-20 04:43:37] laruence@php.net not sure about this, but the current behavior also could be explained. it is always exposed the intern state.. (maybe mark it as final could reslove the confused, but bc break) ------------------------------------------------------------------------ [2015-03-19 20:31:50] grzegorz129 at gmail dot com Description: ------------ Magic method __debugInfo() should be always called while object is printed using var_dump(). Unfortunately it behaves differently if any class in chain extends SPL datastructure - it's simply ignored. Test script: --------------- <?php class foo extends SplStack { public function __debugInfo() { return ['foo']; } } class bar extends foo { public function __debugInfo() { return ['bar']; } } class bar2 extends SplObjectStorage { public function __debugInfo() { return ['bar2']; } } var_dump((new bar), (new bar2)); Expected result: ---------------- object(bar)#1 (1) { [0]=> string(3) "bar" } object(bar2)#2 (1) { [0]=> string(4) "bar2" } Actual result: -------------- object(bar)#1 (2) { ["flags":"SplDoublyLinkedList":private]=> int(6) ["dllist":"SplDoublyLinkedList":private]=> array(0) { } } object(bar2)#2 (1) { ["storage":"SplObjectStorage":private]=> array(0) { } } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69264&edit=1
