Laravel application with Apache gives "use of undefined constant MCRYPT_RIJNDAEL_128 - assumed 'MCRYPT_RIJNDAEL_128'" - apache

Question

I am very new to Laravel and my problems start at the running-my-application stage. For some reason I get this error when I try to access my application at http://127.0.0.1/test/public/ (I have Apache server):
ErrorException in EncryptionServiceProvider.php line 16:

I have mcrypt installed on my system:
[steelrat#archlinux test]$ php -m | grep mcrypt
mcrypt
[steelrat#archlinux test]$ php -i | grep mcrypt
mcrypt
mcrypt support => enabled
mcrypt_filter support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value
Moreover, when I start the artisan web server with php artisan serve and access it with http://localhost:8000, everything works fine. What can be the problem here?
I am aware of this topic: Use of undefined constant MCRYPT_RIJNDAEL_128 - assumed 'MCRYPT_RIJNDAEL_128' . But it doesn't look like my case. The problem with me is that it works with artisan serve and doesn't work with apache.

Answer 1

Depends on your system but there's usually separate php.ini for PHP CLI and PHP Apache.
Add the following to the top of public/index.php
<?php phpinfo(); exit;
That will tell you what extensions mod_php knows about and the location of your loaded php.ini
