Issue: https://github.com/php/php-src/issues/9838 Author: drnkwati ### Description The following code: ```php <?php foreach ([ '2' => 'value' ] as $key => $value) { var_dump($key === '2'); } ``` Resulted in this output: ``` boolean false ``` But I expected this output instead: ``` boolean true ``` Numeric array keys that are specified as string should not be automatically juggled during iterations thanks ### PHP Version PHP 8.0 ### Operating System macOS Ventura 13.0
