Are there alternative methods to retrieve the computer name in PHP without compromising security?

When retrieving the computer name in PHP, the traditional method involves using the `gethostname()` function, which may expose sensitive information about the server environment. To avoid compromising security, an alternative method is to use a configuration variable or environment variable that stores the computer name securely. 

// Retrieve computer name from a secure configuration variable
$computerName = getConfig('computer_name');
echo $computerName;
