How can PHP be used to retrieve the IP address of a DynDNS?

To retrieve the IP address of a DynDNS, you can use PHP to perform a DNS lookup on the domain and extract the IP address from the result. This can be achieved by using the `gethostbyname()` function in PHP, which resolves a hostname to its corresponding IP address. 

$dyndns = 'your-dyndns-domain.com';
$ip_address = gethostbyname($dyndns);

echo "The IP address of $dyndns is: $ip_address";
