如何解决test.php 不会在本地主机上打开，有人可以说是什么问题

上次我问这个问题，问题被关闭，因为它不够清晰，如果问题仍然不清楚，请有人解释为什么不清楚，谢谢！

所以我在 Nginx 文件夹内有一个 test.PHP-> 在 html 文件夹内 https://imgur.com/a/RnnFJ8Q

这是在 test.PHP 中：

<!DOCTYPE html>
<html lang="en">
<head>
    <Meta charset="UTF-8">
    <Meta http-equiv="X-UA-Compatible" content="IE=edge">
    <Meta name="viewport" content="width=device-width,initial-scale=1.0">
    <title>Document</title>
</head>
<body>
    today is a good day
<?PHP echo( 2+2) ?>
</body>
</html>

而且我还在环境变量中创建了 PHP 的路径， https://imgur.com/We7GGZ4 我在 9000 号门上连接了 php-cgi https://imgur.com/glAvSWR 但仍然每次我尝试去 localhost/test.PHP 它说这个 https://imgur.com/0Ac2pYk 但我做了一切正常，为什么它没有显示我在 test.PHP 中的内容我还编辑了 ngnix.conf，部分用于 PHP，这是我的 ngnix.conf：
