nginx（MAMP）在index.php上返回404

I'm trying to use nginx in MAMP but for some reason i can't view any .php file it always returns a 404.

I've got not problem with .html files.

Does someone know what's causing this and how i could solve this ?

My nginx.conf:

#user                         admin staff;
worker_processes             2;

pid        c:/MAMP/bin/nginx/pid/nginx.pid;

events {
    worker_connections       1024;
}

http {
    include                  mime.types;
    default_type             text/html;
    gzip                     on;
    gzip_types               text/css text/x-component application/x-javascript application/javascript text/javascript text/x-js text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;

    sendfile                 on;

    server {
        listen               80 default_server;

        # MAMP DOCUMENT_ROOT !! Don't remove this line !!
