I create a class 'Mylist' that inherits from SplDoublyLinkedList. Mylist has one more public property "type" (integer). When var_dump i want to match the value to a name (from an array). so : final class Mylist extends \SplDoublyLinkedList { /* @var int */ public $type = 0; public function __debugInfo():array { return ['type' => Y::getName($this->type), "dllist" => $this->dllist]; } } When using var_dump, the value for type should be a string returned by Y::getName and NOT the actual 'type' (integer) value. BUT you can put whatever you want in '__debugInfo' it is currently TOTALY IGNORED. (PHP 7.2.2 (cli) (built: Jan 31 2018 19:31:17) ( ZTS MSVC15 (Visual C++ 2017) x64 )) ------------------------------------------------------------------------ [2016-02-17 18:09:39] kb dot minter at gmail dot com This happens with ArrayObject as well. The problem is that internal classes that are extended do not allow for overriding outputting of the internal state. Able to replicate the problem with each PHP version since this functionality has been added... https://3v4l.org/ddq2i For those not wanting to click on an external link... Script: ---------------- <?php class Base extends ArrayObject{ var $parent = true; var $another_prop = 123; public function __construct() { $this['test'] = 123; } public function __debugInfo() { return [ 'parent'=>$this->getArrayCopy() ]; } } class Child extends Base { var $parent = false; } var_dump(new Child()); Expected result: ---------------- object(Child)#1 (1) { ["parent"]=> array(1) { ["test"]=> int(123) } } Actual result: ---------------- object(Child)#1 (3) { ["parent"]=> bool(false) ["another_prop"]=> int(123) ["storage":"ArrayObject":private]=> array(1) { ["test"]=> int(123) } } ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
