-E-commerce web application using php
+E-commerce web application built using php routing. Instead of relying on the web server to map the request path to a file, all requests are forwarded to [index.php](/src/index.php) which has defined routes and callbacks registered to each route. If the request URI is a valid route, the callback returns a page to the user else, redirected to the 404 page.
