What are the challenges of accurately determining the physical location of a server using PHP?

One challenge of accurately determining the physical location of a server using PHP is that the server itself may not have direct access to GPS or other location-based services. One way to solve this is by using a third-party service that provides IP geolocation data. This data can be used to estimate the physical location of the server based on its IP address. 

// Example code using a third-party IP geolocation service to determine server location

$ip = $_SERVER['REMOTE_ADDR'];
$geolocation_data = file_get_contents("http://ip-api.com/json/{$ip}");
$location = json_decode($geolocation_data);

echo "Server is located in: {$location->city}, {$location->regionName}, {$location->country}";
