php not working (source file)

Question

I do not know why php is not working.

I install Nginx and php

  server {

  listen       80;
  server_name  t.com t.com;
  location ~ \.php$  {
   fastcgi_split_path_info ^(.+\.php)(/.+)$;
    root   /var/www/t.com/public_html/;
    index  index.html index.htm;
    try_files $uri $uri/ =404;
    }    error_page   500 502 503 504  /50x.html;
  location = /50x.html {
    root   html;
  }

}

and php.conf

#s
