Homestead 中的 Nginx 配置解析求解

一般情况下 location ~ .php$ 这种模式是匹配不到 index.php/hello 这种路径的，但是homestead里居然可以，求教各位是在哪里有特殊的配置么, 版本是laravel/homestead (virtualbox, 0.4.4)

listen 80;
    listen 443 ssl;
    server_name homestead.app;
    root "/home/vagrant/Code/blog/public";

    index index.html index.htm index.php;

    charset utf-8;

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

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/homestead.app-error.log error;

    sendfile off;

    client_max_body_size 100m;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        fastcgi_intercept_errors off;
        fastcgi_buffer_size 16k;
        fastcgi_buffers 4 16k;
        fastcgi_connect_timeout 300;
        fastcgi_send_timeout 300;
        fastcgi_read_timeout 300;
    }
