-title: Using Nginx for PHP MVC Routing

-An approach for using Nginx to handle all url routing
-for a PHP MVC Framework
-
----

-Last week I was profiling a
-<a href="http://www.php.org" target="_blank">PHP</a> application
-and noticed the overhead of having the url routing written in
-PHP. It is not that the code was poorly written or anything,
-but just seemed like a lot of overhead for the application.
-So, I had an idea what if I moved the url routing to some other
-system that was made for handling url routing? Like,
-<a href="http://nginx.org" target="_blank">nginx</a>.
-
-_Warning:_ My prototype makes the assumption that I am right
-and that nginx is actually faster than PHP for url routing.
-I am yet to do any performance testing, so I may actually be
-wrong here, but thought I'd share my musings anyways.

-```php
-<?php
-$controllerName = $_SERVER['HTTP_PHP_CONTROLLER'];
-$urlParams = array();
-foreach($_SERVER as $name => $value){
-    if(substr($name, 0, 9) == 'HTTP_URL_'){
-        $urlParams[substr($name, 0, 9)] = $value;
-    }
-}
-
-$controller = new $controllerName();
-$controller->handleRoute($urlParams);
-```

-```cfg
-upstream php {
-    server 127.0.0.1:8000;
-    }
-
-server {
-    listen 80;
-    server_name localhost;
-
-    location ~* /model/(?<modelId>[0-9]+)(/.*?\.html)? {
-        proxy_set_header PHP_CONTROLLER "ModelViewController";
-        proxy_set_header URL_MODELID $modelId;
-        proxy_pass http://php;
-    }
-
-    location ~* ^(?<url>/.*)$ {
-        proxy_set_header PHP_CONTROLLER "DefaultController";
-        proxy_set_header URL_URL $url;
-        proxy_pass http://php;
-    }
-}
