How can the phpinfo() function be used to troubleshoot issues with $_GET variables in PHP files?

When troubleshooting issues with $_GET variables in PHP files, the phpinfo() function can be used to check the configuration settings related to variables_order. This setting determines the order in which PHP looks for variables like $_GET, $_POST, etc. By checking the phpinfo() output, you can ensure that $_GET variables are being parsed correctly by PHP.
