How can potential issues with varying URLs be addressed when extracting user origins in PHP?

When extracting user origins in PHP, potential issues with varying URLs can be addressed by using the `parse_url` function to extract the hostname from the URL. This function will normalize the URL and allow you to consistently extract the hostname regardless of the URL format. 

$url = "https://www.example.com/page";
$hostname = parse_url($url, PHP_URL_HOST);
echo $hostname;
