How to Set the PHP Version per Folder?
Do you have a single domain or wish to use different PHP version per folder? Do you have an installed PHP 5.x software in a folder/blog and want to use a PHP 7.x instead? If so, you can do this using cPanel and the .htaccess file.
1. Log into your cPanel account.
2. In the "Software" section, click on the "MultiPHP Manager" icon.
3. Assume that we are new to this and the first thing we will need to do is to get the code generated by cPanel.
4. Scroll down to the end of page, select your domain from the left side and you will see the option "PHP Version" with a drop-down list on the right side. Select the appropriate PHP version from the drop-down menu and click the Apply button.
5. Now open the /public_html/.htaccess file in the cPanel File Manager or in your FTP client and you will find the code generated by cPanel. 
6. After you copy the code, you will wish to set the PHP version to version 7 in the folder/forum, which means you will need to create a .htaccess file in the folder /forum/ and paste the code which was generated in the previous step in it.
7. Congratulations, now your folder/forum uses PHP 7, and if you wish to set any other folder to use the same version of PHP as well, you will only need to copy the code from the .htaccess file and paste it into that folder.
Reset your PHP version from your main domain. If you wish to use a different PHP version on any folder, you will need to follow steps 5 and 6, generate the code, copy that code from /public_html/.htaccess and paste it into any folder where you wish to set your selected PHP version.
