Modifying PHP.INI variables for Joomla on EX2 Ultra

I want to modify some php.ini variables for allowing my Joomla site to upload big files (post_max_size and upload_max_filesize). But when changing /etc/php/php.ini file, it seems that issue remains the same.
Where should I change these variables for my local Joomla site to upload big files?
It seems that this subject is not often answered on forum…
