Problem
You would like to change the options in your application’s php.ini file (ie maximum upload file size), which is hosted in dreamhost.
Solution
Dreamhost is using a file called phprc which is installed in your home directory (~/phprc).

Edit this file and change the setting you would like.
Problem
You are trying to install the dependencies in a PHP Symfony project, but you get an error about enable extensions in ini files.
Solution
Make sure that you install the correct packages for the PHP version you are using. So installing php-curl while using PHP 7.1 results in the error.
When installing php7.1-curl the installation completes successfuly.
