What function in PHP can be used to retrieve information about the host connection?

To retrieve information about the host connection in PHP, you can use the $_SERVER superglobal array. Specifically, you can use the $_SERVER['REMOTE_ADDR'] key to get the IP address of the client making the request. This can be useful for logging, security checks, or customizing content based on the user's location. 

// Retrieve the IP address of the client
$ipAddress = $_SERVER['REMOTE_ADDR'];

// Output the IP address
echo "Client IP Address: " . $ipAddress;
