运行服务httpd重启后，我无法在本地环境中运行项目

通过使用命令service httpd restart运行httpd后，但我无法在本地运行项目。在运行项目时，它会显示PHP代码。你能帮我解决这个问题吗?这是PHP代码:

<?php// allow testing from the upgrade page before the site is upgraded.if (isset($_GET['__testing_rewrite'])) {
if (isset($_GET['__elgg_uri']) && false !== strpos($_GET['__elgg_uri'], '__testing_rewrite')) {
    echo "success";
}
exit;}require_once(dirname(__FILE__) . "/engine/start.php");$router = _elgg_services()->router;$request = _elgg_services()->request;if (!$router->route($request)) {
forward('', '404');}
