This guide explains how to change the server configuration of a site with a Web hosting and a managed Cloud Server.

The difference between the .user.ini and .htaccess files

• Apache is the HTTP server. It is configured with a .htaccess file placed at the root of the website.
• PHP is a programming language used to create dynamic web pages via an HTTP server. It is possible to customise your PHP commands with a .user.ini , which will be effective in the folders and subfolders where the .user.ini file is placed.

We are now going to show 3 ways of changing the server configuration for a site.

1. Changing the PHP configuration via the console

Certain settings (e.g. allow_url_fopen or memory_limit) can be configured via the console:

1. Open the admin console (https://admin2.infomaniak.com)
2. Go to Hosting
3. Click on the relevant hosting/domain name
4. Under Sites, click on the relevant site's domain name
5. adjust the site configuration as needed

The following example allows the memory available for PHP to be changed:

2. Changing the PHP configuration via the .user.ini file

To customise the PHP commands via a web browser, the values required need to be specified in a .user.ini file

The following example allows the max_input_vars variable to be changed:

max_input_vars=3000

3. Changing the PHP configuration via CLI

To customise PHP commands via a command line interface (CLI) or in CRON tasks,the values required need to be specified in a .user.ini file the executable PHP then needs to be called with the -c .user.ini option

The following example allows the memory available for PHP to be changed:

~/web$ echo -e '<?php echo "memory_limit: " . ini_get("memory_limit") . "n"; ?>' >memory-limit.php
~/web$ php memory-limit.php
memory_limit: 512M
~/web$ echo 'memory_limit = 1024M' >.user.ini
~/web$ php -c .user.ini memory-limit.php
memory_limit: 1024M
~/web$
