To set a different PHP version for an addon domain, you need to add a special code to your .htaccess file. To do this, follow the steps below.
1. Find the .htaccess file for the addon domain in question. The steps for how to find it can be located here.
2. Add the following line to your .htaccess file:
<FilesMatch ".(?:html|php)$"> SetHandler application/x-lsphpXX
For servers with LiteSpeed the code should be the following:
<FilesMatch ".(?:html|php)$"> SetHandler application/x-httpd-alt-phpXX
where XX is the PHP version you wish to set. It can be 52, 53, 54, 55, 56, 70, 71,72, 73, 74, 80 or 81.
For example:
You need to download the php.ini file for different PHP versions from the Attachments section at the end of this guide. Do not forget to rename the file to php.ini once it is uploaded to the hosting account.
Alternatively, you can run the command below via SSH:
cp /opt/alt/default_php_ini/phpXX.ini /home/cPanel_username/path_to_the_folder/php.ini
- XX is PHP version you wish to set (it can be 52, 53, 54, 55, 56, 70, 71, 72, 73, 74, 80 or 81),
- cPanel_username should be replaced with your actual cPanel username, and
- path_to_the_folder is a path to the folder of the addon domain.
For example:
The process is similar if you wish to set a different PHP version for a subdomain.
