[php-src] Issue #9511: php empty function corner case?

Issue: https://github.com/php/php-src/issues/9511 Author: 8ctopus ### Description The following code: ```php <?php class myClass { private string $myString; public function __construct() { $this->myString = 'hello'; } public function __get(string $property) : mixed { if (property_exists($this, $property)) { return $this->{$property}; } throw new Exception("unknown property {$property}"); } } $myClass = new myClass(); echo (empty($myClass->myString) ? 'property is empty' : 'property not empty') . PHP_EOL; echo 'strlen: ' . strlen($myClass->myString); ``` Resulted in this output: ``` property is empty strlen: 5 ``` But I expected this output instead: ``` property not empty strlen: 5 ``` https://onlinephp.io/c/fb939 ### PHP Version 8.2.0beta3 and 8.1.10 ### Operating System /
