location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
        if (!-f $document_root$fastcgi_script_name) {
                return 404;
        }

        fastcgi_pass 127.0.0.1:9000;
        #fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
}

基本上只要在server裡加上這段就可以了，但要注意fastcgi參數一定要有SCRIPT_FILENAME，不然PHP會回傳空白頁面，這可以加在fastcgi_params或者location裡頭

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
