Description: ------------ When unsetting object property it unsetted from object then __get method of object is called while accessing it. Besides property exists in all reflection objects (ReflectionObject and ReflectionProperty) but cause Fatal error while getting it. Reproduce code: --------------- <?php class B{} class A { public $Var = null; public function __construct() { $this->Var= new B(); } public function __get($name) { echo "get {$name}\n"; if(isset($this->Var)) { return $this->Var; } else { echo "Undefined variable\n"; return null; } } public function __unset($nm) { echo "unset"; } } $a = new A(); unset($a->Var); $o = new ReflectionObject($a); $p = $o->getProperty('Var'); Reflection::export($o);//Variable Exists Reflection::export($p);//Variable Exists var_dump($a->Var);//__get called var_dump($p->getValue($a)); //Fatal error ?> Expected result: ---------------- $o = new ReflectionObject($a); has correct current instance properties or $p->getValue($a) - will call __get method too and not cause fatal error. Actual result: -------------- Object of class [ <user> class A ] { @@ D:\WWW\www.usoftinc.com\test2.php 3-27 - Constants [0] { } - Static properties [0] { } - Static methods [0] { } - Properties [1] { Property [ <default> public $Var ] } - Dynamic properties [0] { } - Methods [3] { Method [ <user, ctor> public method __construct ] { @@ D:\WWW\www.usoftinc.com\test2.php 6 - 9 } Method [ <user> public method __get ] { @@ D:\WWW\www.usoftinc.com\test2.php 10 - 22 - Parameters [1] { Parameter #0 [ <required> $name ] } } Method [ <user> public method __unset ] { @@ D:\WWW\www.usoftinc.com\test2.php 23 - 26 - Parameters [1] { Parameter #0 [ <required> $nm ] } } } } Property [ <default> public $Var ] get Var Undefined variable NULL <br /> <b>Fatal error</b>: Internal error: Could not find the property Var in <b>test2.php</b> on line <b>36</b><br /> -- Edit bug report at http://bugs.php.net/?id=38640&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38640&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38640&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38640&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38640&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38640&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38640&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38640&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38640&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38640&r=support Expected behavior: http://bugs.php.net/fix.php?id=38640&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38640&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38640&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38640&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38640&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38640&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38640&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38640&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38640&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38640&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38640&r=mysqlcfg
