===== nginx =====
The **nginx** webserver is a fast and powerfull webserver, which usually used in production for loadbalancing.

=== Configuraiton PHP+nginx on Windows ===

Here is the describiton: \\
https://eksith.wordpress.com/2008/12/08/nginx-php-on-windows/

On Windows7 x64 a lib **Visual C++ Redistributable for Visual Studio 2012 Update 4** has to be installed, for php-cgi.exe to work.
Otherwise it throws an exception 
<code>The program can't start because MSVCR110.dll is missing from your computer. Try reinstalling the problem to fix this problem."</code>

**Both versions, 32 and x64** bit have to be installed for the php-cgi to work: \\

==== PHP configuraiton ====
Php in configured in php.ini. You can check where it should be located by checking the *Configuration File (php.ini) Path* among the output of
<sxh=php >
<?php
 phpinfo();
?>
</sxh>

Alternatively you can pass the php.ini explicitely to the service **php-cgi** which serves the cgi requests.

<code>
"c:\nginx\php\php-cgi.exe" -b 127.0.0.1:9000 -c c:\Windows\php.ini
</code>


==== nginx.conf ====

This config redirects all requests with all methods (GET, POST, PUT, DELETE) to the file index.php.
The originally requested path may be retrieved from the **$_SERVER** variable.
The **GET / POST** parameters are available as well.

<code>

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;

		# this guy redirects any path to /api.json
		rewrite ^.*$ /index.php last;

        location / {
            root   html;
            index  index.php index.html index.htm;
			try_files $uri $uri/ /index.php;
        }

        # redirect server error pages to the static page /50x.html
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include        fastcgi_params;
			set $path_info  $uri;
			fastcgi_param PATH_INFO $fastcgi_script_name;
        }
    }

}

</code>


To retrieve the requested method do the following inside the **index.php**

<code>
<?php
	echo "hello \n";
		
	# requested method (PUT GET POST DELETE)
	echo getServerVariable('REQUEST_METHOD') . "\n";
	
	# REQUEST_URI as string
	$requesturi 		= getServerVariable('REQUEST_URI');
	echo requesturi . "\n";
	
	# REQUEST_URI as an array of path segments
	$requesturiArray = explode('/', $requesturi);
	echo implode($requesturiArray) . "\n";
	
	
	function getServerVariable($variable){
		if(isset($_SERVER[$variable])){
			$pmethod = $_SERVER[$variable];	
			return $pmethod;
		}else{
			return "$variable undefined";
		}
	}

?>
</code>

#   - The $proxy_connection variable is used in a proxy_set_header directive in
