What are the benefits of using dummy domains like example.com in code examples?

Using dummy domains like example.com in code examples is beneficial because it ensures that the code remains generic and can be easily understood by readers without getting distracted by specific domain names. It also prevents accidental clicks or interactions with real websites when testing the code. Additionally, using dummy domains helps to maintain the focus on the functionality being demonstrated rather than the specific URLs involved.

// Using dummy domain example.com in a code example
$url = 'http://example.com/api/data';
$response = file_get_contents($url);
echo $response;
