How important is it to ensure that the PHP version on the local machine matches the one on the server?

It is crucial to ensure that the PHP version on the local machine matches the one on the server to avoid compatibility issues and potential errors when deploying code. You can check the PHP version on your local machine by running `php -v` in the terminal. If the versions do not match, you should update the PHP version on your local machine to match the one on the server.

<?php
// Check PHP version on local machine
echo phpversion();
?>
