This is a basic configuration to work with php5.6 with nginx on Linux

nginx.conf.example

server {
	listen   80; 
  
  	error_log /var/log/nginx/php5.log error;
	root  /var/www/html;
	index index.php index.html index.htm;

	server_name example.local;

  	# You would need this line if you want to allow CORS on your server
  	add_header 'Access-Control-Allow-Origin' *;

	location / {
		# try_files $uri $uri/ =404;
    		try_files $uri $uri/ /index.php$is_args$args;
	}

	location /doc/ {
		alias /usr/share/doc/;
		autoindex on;
		allow 127.0.0.1;
		deny all;
	}

	#error_page 404 /404.html;

	location ~ \.php$ {
		fastcgi_split_path_info ^(.+\.php)(/.+)$;
		# NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

		# With php5-cgi alone:
		# fastcgi_pass 127.0.0.1:9000;
    
		# With php5.6-fpm:
		fastcgi_pass unix:/var/run/php/php5.6-fpm.sock;
		fastcgi_index index.php;
		include fastcgi_params;
		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
	}
