Editing the server configuration of a site (.user.ini ; .htaccess)

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 in 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 the PHP commands using a .user.inifile, these changes will be effective in the folder and sub-folders where the .user.ini file is located

Important:

modification of the .user.ini file requires several minutes to be effective
the PHP commands must imperatively be placed in the .user.ini file to be taken into account

We will now illustrate 3 ways to modify the server configuration of a site.

1. Changing the PHP configuration via Manager

Certain settings (e.g. allow_url_fopen or memory_limit) can be configured via Manager

open Manager (manager.infomaniak.com)
go to Hosting
click on the hosting/domain name concerned
under Sites below click on the domain name of the site concerned
click on Advanced parameters
under the PHP and Apache tabs, adjust the configuration of the site as needed
save

sign

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

To customise the PHP commands using a Web browser, you must define the values desired in the .user.ini file

The following example illustrates changing the max_input_vars variable

max_input_vars=3000

3. Changing the PHP configuration in CLI

To customise the PHP commands using command line interface (CLI) or in CRON tasks, you must define the desired values in a .user.ini file and than call the PHP executable with the -c .user.inioption

The following example illustrates changing the memory available for PHP:

~/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$

The following example activates allow_url_fopen for the WP CLI tool (specifically allows recovering extensions):

php -d allow_url_fopen=On ~/bin/wp package install trepmal/wp-revisions-cli
