You can copy a server level php.ini from /usr/local/lib/php.ini into a folder say /home/user/phpconfig and then add the line below to the .htaccess file of your account.
Code:
suPHP_ConfigPath /home/user/phpconfig
You can then update the variable upload_max_filesize in this local file to 5GB.
Note: You are allowed to use a local php.ini if you are running SuPHP. You can confirm and/or change this in WHM under the tab "Service Configuration >> Apache Configuration >> Configure PHP and SuExec > PHP 5 Handler".

The problem is: I am creating a website where users can upload files, everything is working great, but these files can be up to 5GB. Is there a possibility to set a php.ini for one user? So that my account got limits of 5GB while others still got limits of 8MB?
Thanks,
