How can IP addresses be used in PHP to distribute uploaded files across multiple servers?

To distribute uploaded files across multiple servers using IP addresses in PHP, you can use a load balancer that routes requests based on the client's IP address to different servers. This way, you can evenly distribute the load and prevent any single server from becoming overwhelmed. 

// Sample code to distribute uploaded files across multiple servers using IP addresses
$ip_address = $_SERVER['REMOTE_ADDR'];

if ($ip_address == '192.168.1.1') {
    // Upload file to Server 1
    move_uploaded_file($_FILES['file']['tmp_name'], '/path/to/server1/uploads/' . $_FILES['file']['name']);
} elseif ($ip_address == '192.168.1.2') {
    // Upload file to Server 2
    move_uploaded_file($_FILES['file']['tmp_name'], '/path/to/server2/uploads/' . $_FILES['file']['name']);
} else {
    // Handle other IP addresses or implement additional logic
    echo 'Invalid IP address';
}
