What is the purpose of displaying the IP address in a signature using PHP?

Displaying the IP address in a signature using PHP can be useful for tracking user activity, troubleshooting technical issues, or verifying user identity. It can also provide a level of security by allowing administrators to monitor and detect any suspicious or unauthorized access.

// Get the user's IP address
$ip_address = $_SERVER['REMOTE_ADDR'];
