Are there alternative methods to retrieve the host information in PHP if $_SERVER['REMOTE_HOST'] is not working?

If $_SERVER['REMOTE_HOST'] is not working, an alternative method to retrieve the host information in PHP is to use the gethostbyaddr() function. This function takes an IP address as input and returns the corresponding host name. By using gethostbyaddr(), you can still retrieve the host information even if $_SERVER['REMOTE_HOST'] is not functioning properly. 

$ip = $_SERVER['REMOTE_ADDR'];
$host = gethostbyaddr($ip);

echo "Host: " . $host;
