What role do vhosts play in the context of modifying php.ini settings and PHP extensions on a server managed by Plesk?

Vhosts in Plesk allow you to modify PHP settings and enable/disable PHP extensions on a per-domain basis. This means you can customize the PHP configuration for each website hosted on your server. To modify php.ini settings or enable PHP extensions for a specific domain, you need to access the vhost configuration file for that domain in Plesk.

// Example code snippet to modify PHP settings in vhost configuration file in Plesk
// Open the vhost configuration file for the domain
// Add or modify the necessary PHP settings or extensions
// Save the changes and restart the web server for the changes to take effect
