Bug #72174 [NEW]: ReflectionProperty#getValue() causes __isset call

From: ocramius at gmail dot com Operating system: PHP version: 7.0.6 Package: Reflection related Bug Type: Bug Bug description:ReflectionProperty#getValue() causes __isset call Description: ------------ When using ReflectionProperty#getValue($object) on a $object with an unset() property and defined __isset and __get methods, the __get method is called, while it should only use __get. Note that this is a bug that affects only PHP 7.0.6, and isn't part of 7.0.5. Test script: --------------- <?php class Foo { private $bar; public function __construct() { unset($this->bar); } public function __isset($name) { var_dump(__METHOD__); return true; } public function __get($name) { var_dump(__METHOD__); return $name; } } $instance = new Foo(); $reflectionBar = (new ReflectionProperty(Foo::class, 'bar')); $reflectionBar->setAccessible(true); $closureBar = (function (Foo $instance) { return $instance->bar; })->bindTo(null, Foo::class); var_dump($reflectionBar->getValue($instance)); var_dump($closureBar($instance)); Expected result: ---------------- string(10) "Foo::__get" string(3) "bar" string(10) "Foo::__get" string(3) "bar" Actual result: -------------- string(12) "Foo::__isset" string(10) "Foo::__get" string(3) "bar" string(10) "Foo::__get" string(3) "bar" -- Edit bug report at https://bugs.php.net/bug.php?id=72174&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72174&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72174&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72174&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72174&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72174&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72174&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72174&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72174&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72174&r=support Expected behavior: https://bugs.php.net/fix.php?id=72174&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72174&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72174&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72174&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72174&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72174&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72174&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72174&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72174&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72174&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72174&r=mysqlcfg
