How can beginners troubleshoot URL parsing issues in PHP code?

Beginners can troubleshoot URL parsing issues in PHP code by using the built-in function `parse_url()` to break down the URL into its components such as scheme, host, path, etc. This function helps in identifying any errors in the URL structure and allows for easier manipulation of the URL components. 

$url = "https://www.example.com/path/to/page?query=123";
$parsed_url = parse_url($url);

echo "Scheme: " . $parsed_url['scheme'] . "<br>";
echo "Host: " . $parsed_url['host'] . "<br>";
echo "Path: " . $parsed_url['path'] . "<br>";
echo "Query: " . $parsed_url['query'] . "<br>";
