VPS: How to Change PHP Version and Configure PHP Settings

If you are running a VPS server and have CentOS 7 or Ubuntu installed and are using cPanel, you can use the instructions below to help you change the PHP version and settings.

In your hosting package, you can specify the desired PHP version for each domain or subdomain individually, and you can also change other PHP settings.

1. How do I change the PHP version for an individual domain or subdomain?
2. How do I change the PHP settings?
   • Change PHP settings in the editor
   • Manually change additional PHP settings
3. How do I check the selected PHP version and settings?

1. How do I change the PHP version?

You can do this in the cPanel -> Software -> MultiPHP Manager icon.

In the list , tick the domain or subdomain you want to change the PHP version for and select the desired version from the drop-down menu (top right). Then click the Apply button to apply the changes.

The currently selected PHP version for each domain or subdomain can be seen in the list.

You can check which changes have been made for the currently selected version in various files (for example, php.ini and .htaccess files) located in the folder where the domain is directed (in the case of the hosting package’s carrier domain, it is directed to the public_html folder). If you do not see these files, you can also turn on the display of hidden files and folders.

The simplest way to access the files is via cPanel -> Files section -> File Manager icon.

An example of a php.ini file can be seen below. The selected PHP version is written in the session.save.path line, where the selected version(php74) is specified at the end, so in this case PHP 7.4.

2. How do I change the PHP settings?

You can also edit the PHP settings for an individual domain or subdomain in the cPanel -> Software -> MultiPHP INI Editor icon.

a) Changing PHP settings in the editor

You can easily change the PHP settings for a domain or subdomain in the editor (under the Basic Mode tab, which is already selected by default). Select the desired domain or subdomain from the list below to see the options for changing PHP settings.

In the list , change the desired settings and then click the Apply button below to apply the changes.

b) Manually change PHP settings

You can also change the PHP settings for a domain or subdomain manually (under the Editor Mode tab). Select the desired domain or subdomain from the list below to display the editor where you can change the PHP settings.

You can then edit the PHP settings in the editor that appears. Then click the Save button to apply the changes.

3. How do I check the PHP version and settings?

You can check which PHP version is selected and what the current PHP settings are in the editor where you made the changes.

You can also check all PHP settings by creating a .PHP file with any name (for example, test.php) in the folder where the domain is pointed and writing the function: <?php phpinfo(); ?>

The file you have created can be viewed in a browser (enter the path to the file in the URL, for example https://vasadomena.si/test.php), where you can check the PHP version you have chosen and other PHP settings.
