如何升级到最新版本的PHP 5.4.10（当前稳定）？

在我的 PHP 应用程序中：

die($_SERVER['SERVER_NAME']);

请求：

sub1.example.com

结果：

example.com

我的 NGINX 配置：

server
{
    server_name .example.com;
    access_log /var/log/nginx/example.com.access.log;
    error_log /var/log/nginx/example.com.error.log;
    root /var/www/html/example;
    index index.php;

    location ~ \.php$ {
        if (-f $request_filename) {
            fastcgi_pass    127.0.0.1:9000;
        }
        fastcgi_index   index.php;
        fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include         fastcgi_params;
    }

    location / {
        if ($request_filename ~ /sub1) {
            rewrite ^ http://sub1.example.com/? permanent;
        }
        if ($request_filename ~ /sub2) {
            rewrite ^ http://sub2.example.com/? permanent;
        }
        if (!-f $request_filename) {
            rewrite ^(.*)$ /index.php last;
        }
    }
}

为什么子域没有在 php 中被拾取？
