How can PHP be used to track and restrict the traffic for a specific folder on a server?

To track and restrict traffic for a specific folder on a server using PHP, you can create a script that checks the IP address of the incoming requests and either allows or denies access based on predefined rules. This can help prevent unauthorized access to sensitive files or directories.

<?php
$allowed_ips = array('192.168.1.1', '10.0.0.1'); // Define allowed IP addresses

$ip = $_SERVER['REMOTE_ADDR']; // Get the IP address of the incoming request

if (!in_array($ip, $allowed_ips)) {
    header('HTTP/1.1 403 Forbidden');
    echo 'Access Forbidden';
    exit;
}

// Code to execute if the IP address is allowed
// For example, include the files in the restricted folder
include('restricted_folder/file.php');
?>
