[php-src] Issue #11851: Erroneous call of magic functions on class variables, erroneous assignment of data to a variable

Issue: https://github.com/php/php-src/issues/11851 Author: AlexeyZamorov ### Description The following code: ```php <?php class TClass { public function something() : array { unset(self::$Cache->Content); return []; } public static TCache $Cache; } TClass::$Cache = new TCache(); class TCache { public function __destruct() { if(isset($this->Hash, $this->Content)) {} } public function &__get(string $name) { if(!isset($this->Content)) { $this->Content = []; $this->Hash = false; } return $this->Content; } public function __set(string $name, string|array|false $value) : void { $this->Content = $value; // this code is failing $this->Hash ??= false; //this code works correctly //if(!isset($this->Hash)) { $this->Hash = false; } } public function __isset(string $name) : bool { if(!isset($this->Content)) { $this->__get($name); } return isset($this->Content); } public function __unset(string $name) : void { unset($this->Content, $this->Hash); } protected string|array|false $Content; protected string|false $Hash; } (new TClass())->something(); ``` Resulted in this output: ``` PHP Fatal error: Uncaught TypeError: Cannot assign array to property TCache::$Hash of type string|false in test.php:38 Stack trace: #0 test.php(26): TCache->__set('Content', Array) #1 test.php(48): TCache->__get('Content') #2 test.php(46): TCache->__isset('Content') #3 test.php(19): TCache->__isset('Hash') #4 [internal function]: TCache->__destruct() #5 {main} thrown in test.php on line 38 Process finished with exit code 255 ``` But I expected this output instead: ``` Process finished with exit code 0 ``` ### PHP Version 8.1.21 ### Operating System FreeBSD 13.2
