将 wordpress 移动到子域时出错

将WordPress移动到子目录中并得到此错误：

致命错误：函数名称必须是 /home/content/61/11855861/html/wordpress/index.php 在第 17 行

这是我的代码：

<?php
/**
 * Front to the WordPress application. This file doesn't do anything, but loads
 * wp-blog-header.php which does and tells WordPress to load the theme.
 *
 * @package WordPress
 */
/**
 * Tells WordPress to load the WordPress theme and output it.
 *
 * @var bool
 */
define('WP_USE_THEMES', true);
/** Loads the WordPress Environment and Template */
require $wordpress ('/wordpress/wp-blog-header.php');
