Managing Extensions for PHP, Perl, Python
Additional extensions are often required to work with web programming languages, for example, for forums or online stores.
For example, you need to set up or change a PHP extension. To do that, use the Web Server Settings menu, click on the required PHP version, and press the Extensions link.

Enable only the extensions that are needed for your scripts, and do not add any unnecessary ones as they consume the server’s resources.
