Laravel Lumen: NotFoundHttpException after installation

After a fresh installation of Laravel Lumen, I got a NotFoundHttpException for the index route. I copied the .env.example  file to .env  and set up the APP_KEY. But I still got the NotFoundHttpException.

After searching the internet for some time I found out these steps:

In public/index.php change the last line to this:

persistent language prefixing with laravel

Here I want to describe how to build up a persistent language prefixing for your URLs in Laravel.

This technique requires, that the routes are named! This is just a quick sketch, and not fully complete!

In the app::before filter I detect the language. If no language was detected I redirect to the default language.

The Routes are working with a locale pattern. Here is an example:

In my global.php (e.g.) I put a new route() function and the function to do a language switch. The language switch changes just the current language but keeps the current page displayed.

PHP profiling with Xdebug

Best is to enable Xdebug with a trigger, that is added by a .htaccess. With this method I can profile a single application within my development environment.

Xdebug settings

To make use of Xdebug I need to add a GET, POST or COOKIE variable with the name XDEBUG_PROFILE.

I use a .htaccess in my project root to add the specified GET parameter.

.htaccess Example

 Analyzing the Output

On my Windows 7 maschine I use WinCacheGrind to analyze the profiler output.
