if ( !isset($wp_did_header) ) {// 为了首次加载才执行

    $wp_did_header = true;// 定义个标志咯

    require_once( dirname(__FILE__) . ‘/wp-load.php‘ );// 获取文件目录后生成绝对路径

    wp();// wp-load.php 里面require了/wp-admin/setup-config.php，/wp-admin/setup-config.php里面 require了/wp-admin/wp-settings.php，/wp-admin/wp-settings.php require 了class-wp.php ，得到了WP 类，然后执行$GLOBALS[‘wp‘] = new WP() 得到一个实例；

require_once( ABSPATH . WPINC . ‘/template-loader.php‘ );// 加载templateloader.php 文件 }
