Is it recommended to use example.com or similar domains for illustrative purposes in PHP code?

It is recommended to use example.com or similar domains for illustrative purposes in PHP code to prevent unintentional interaction with real websites or services. This practice helps to avoid any potential security risks or conflicts that may arise from using actual domain names in code snippets.

// Good practice: Using example.com for illustrative purposes
$url = 'http://www.example.com/api/data';
