Nginx - PHP 从不渲染。Html 文件运行良好

Question

当我输入 PHP 文件时，它们会永久加载。但不会显示在浏览器中。几分钟后，浏览器就会超时。

Html 文件可以正确显示/呈现。

这是我的虚拟主机：

server {
    listen 80;
    
        server_name localhost;

    root /var/www/site;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }
}

以下是 www.conf 中最重要的内容：

listen = /var/run/php/php7.2-fpm.sock
user = www-data
group = www-data

在 php.ini 中我有：

cgi.fix_pathinfo=0

当然，我重启了 php 和 nginx。我不知道问题出在哪里

版本：

nginx version: nginx/1.18.0 (Ubuntu)
PHP 7.2.34-36+ubuntu20.04.1+deb.sury.org+1 (cli) (built: Oct 28 2022 18:25:54) ( NTS )

有人可以帮忙吗？
