What is the difference between $_GET['section'] and mod_rewrite in PHP?

$_GET['section'] is used to retrieve the value of a parameter passed through the URL, while mod_rewrite is a technique used to rewrite URLs for better readability and SEO purposes. If you want to use mod_rewrite to rewrite URLs and have cleaner URLs, you can achieve this by creating rewrite rules in your .htaccess file. This allows you to have URLs like example.com/section instead of example.com/?section=value.

RewriteEngine On
RewriteRule ^section$ index.php?section=value [L]
