Bug #69264 [Com]: __debugInfo() ignored while extending SPL datastructures

Edit report at https://bugs.php.net/bug.php?id=69264&edit=1 ID: 69264 Comment by: grzegorz129 at gmail dot com Reported by: grzegorz129 at gmail dot com Summary: __debugInfo() ignored while extending SPL datastructures Status: Feedback Type: Bug Package: SPL related Operating System: All PHP Version: 5.6.6 Block user comment: N Private report: N New Comment: It should NOT be marked as final I think. I noticed that strange behaviour during actual usage of SplObjectStorage with really deep objects. Using __debugInfo() to print only object ids is a bless. Previous Comments: ------------------------------------------------------------------------ [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
