In what situations should you consider checking for the visitor's IP address in PHP scripts?

Checking for the visitor's IP address in PHP scripts can be useful in situations where you need to track or restrict access based on the user's location or prevent malicious activities such as spamming or hacking. By obtaining the visitor's IP address, you can gather valuable information about their geographical location and device, which can help in personalizing user experiences or enhancing security measures. 

<?php
// Get visitor's IP address
$ip_address = $_SERVER['REMOTE_ADDR'];

// Print the IP address
echo "Your IP address is: " . $ip_address;
?>
