I was searching the web and i found a few lines of code that ip lock a page to you're ip and redirect you to any link if you are not the owner.

PHP Code


<?php
    $ip = $_SERVER['HTTP_CLIENT_IP'];
    if($ip!="IP Goes Here") {
        Header("Location: http://google.com");
?>

I don't know if this has been seen on hf but i had to share it just in case it wasn't :)

Here's one better:

PHP Code


<?php
session_start();
// Check if hidden behind Cloudflare
if (isset($_SERVER["HTTP_CF_CONNECTING_IP"])) {
  $_SERVER['REMOTE_ADDR'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
}
$ip = $_SERVER['REMOTE_ADDR'];
$allowed_ips = array('admin_home' => '255.255.255.255');
foreach($allowed_ips as $auth_name => $auth_ip) {
if($auth_ip != $ip) {
     exit('You are not authorized to see this page.');
} else if($auth_ip == $ip) {
     $_SESSION['auth_name'] = $auth_name;
     $_SESSION['auth_ip'] = $auth_ip;
}
}
// Display page content down here, since we're authorized to see it.
?>

Now, what if we're not at home?

PHP Code


<?php
$auth_keys = array('1234567890abcedefghijklmnopqrstuvwxyz');
$auth_attempt = $_GET['auth']; // using get, but easy change to $_POST
if(!in_array($auth_attempt, $auth_keys)) {
     exit('You are not authorized to view this page.');
}
// Assumes we're authorized if we can still view page.
?>

Also don't just use header() add exit or die they can ignore the header location...
