What alternative method can be used to access the IP address of a user in PHP?

To access the IP address of a user in PHP, you can use the `$_SERVER['REMOTE_ADDR']` superglobal variable. This variable contains the IP address of the user making the request to the server. By accessing this variable, you can retrieve the IP address of the user accessing your PHP script.

$user_ip = $_SERVER['REMOTE_ADDR'];
echo "User IP Address: " . $user_ip;
