How can I find the version of php that is running on a distinct domain name?

There are a few ways to find out the version of PHP running on a specific domain name. One way is to create a PHP script with the following code:

<?php
phpinfo();
?>

Watch a course Learn object oriented PHP

Then upload this script to the root directory of the domain you want to check, and access it via your web browser by visiting the script's URL (e.g., www.example.com/phpinfo.php). This will display a page containing information about the server's PHP configuration, including the version number. Another way is to access the server via command line and type php -v this will give you the version of PHP running on the server.
