In Laravel 4 , we have a configuration file app/config/app.php .
There is an option called url . Many times I've seen this option empty:
'url' => '',
And also I've already tested put some url there:
'url' => 'http://meusite.com'
But I noticed that this did not change the links in my application. This happened in Laravel 3 .
So, what is the purpose of this option url in the file app/config/app.php ?
As far as I know, this setting has the purpose of defining which is the base url of the application when it is not possible to detect it automatically.
A basic example of this is running on the command line.
Consider the following example using the tinker command (Laravel on the iterative mode command line) of artisan .
First I leave the configuration file app/config/app.php like this:
// Outras definições ...
'url' => ''
Then I do this on the command line:
php artisan tinker --env=local
> URL::to('/test');
The result returned is: '/test'
Now we change the configuration file again. This time I'll put a default url.
Example:
// Outras definições ...
'url' => 'http://stackoverflow.com.br/',
We run tinker again:
php artisan tinker --env=local
> URL::to('/test');
The result is: 'http://stackoverflow.com.br/test' ;
So, notice that, in the absence of a "base url" for the system, Laravel will use this url set to app/config/app.php as the base url.
