Bug #71838 [Opn]: Deserializing serialized SPLObjectStorage-Object can't access properties in PHP

Edit report at https://bugs.php.net/bug.php?id=71838&edit=1 ID: 71838 User updated by: andreas at heigl dot org Reported by: andreas at heigl dot org -Summary: 39 +Summary: Deserializing serialized SPLObjectStorage-Object can't access properties in PHP Status: Open Type: Bug Package: SPL related Operating System: 3v4l.org PHP Version: 7.0.4 Block user comment: N Private report: N New Comment: - Previous Comments: ------------------------------------------------------------------------ [2016-03-16 15:21:11] andreas at heigl dot org Removing the "extends SPLObjectStorage" fixes the issue as can be seen at https://3v4l.org/SjBmY ------------------------------------------------------------------------ [2016-03-16 15:16:10] andreas at heigl dot org Description: ------------ It seems that with PHP7 (and HHVM) deserializing a serialized SPLObjectStorage-Object results in an Object that can not access the properties any more. The properties seem to be there (somehow) as a "var_Dump($obj)" shows them, but methods from inside the newly created object can't access those values any more. I've created a test-script at https://3v4l.org/LCmI2 to illustrate the case. Am I missing something? I could not find a reference to this behaviour but I might just not have searched for the right terms... Test script: --------------- <?php class A extends SplObjectStorage { protected $a = null; public function __construct() { $this->a = '123'; } public function getA() { return $this->a; } } $serialized = serialize(new A()); $obj = unserialize($serialized); $reader = function & ($object, $property) { $value = & \Closure::bind(function & () use ($property) { return $this->$property; }, $object, $object)->__invoke(); return $value; }; $test3 = & $reader($obj, 'a'); echo "Result from Getter\n"; var_dump($obj->getA()); echo "Result from Reflection\n"; var_Dump($test3); echo "This is the deserialized Object\n"; var_Dump($obj); Expected result: ---------------- I'd expect the same output in PHP7 as in PHP5.6 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71838&edit=1
