REQUEST_URI错误：出现在functions.php神秘的73行

Warning: Use of undefined constant REQUEST_URI – assumed ‘REQUEST_URI’ (this will throw an Error in a future version of PHP) in /var/www/web/wp-content/themes/slatudou/functions.php on line 73

这个奇怪的错误，到底是为什么呢

打开funcitons.php第73行，代码如下：文章源自原紫番博客-https://www.yuanzifan.com/54311.html

$path = $_SERVER['HTTP_HOST'] . $_SERVER[REQUEST_URI];

注意到什么问题了么，一边少了一个单引号：REQUEST_URI的左右。文章源自原紫番博客-https://www.yuanzifan.com/54311.html

加上双引号，问题解决：文章源自原紫番博客-https://www.yuanzifan.com/54311.html

<pre>$path = $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];</pre>
