如果没有引用并重定向流量类型，则重定向

Question

I'm trying to load content from a different page if the user came to the page with NO referrer or if the user types my page in directly.

This is the code I would like to alter to be able to achieve this.

The code below redirects based on if the user has 1 of the IPs listed below, it will load the fakepage.php. I would like to alter this script so it can work if there is NO referrer, or if the user types in my url directly.

<?php
$banned = array('56.150.186.229','89.103.221.49');
$userIP = $_SERVER['SERVER_ADDR'];
if(in_array($userIP,$banned)) {
include_once('fakepage.php');
} else {
include_once('realpage.php');
}
?>

I'm trying to make this look as seamless as possible, so the user will not know they were redirected

Answer 1

Use $_SERVER['REMOTE_ADDR'] to get the users ip (you may need another header if you are running behind a proxy or similar. Then check to see if $_SERVER['HTTP_REFERER'] is empty for your second condition.

 $banned = array('56.150.186.229','89.103.221.49');
 $userIP = $_SERVER['REMOTE_ADDR']; // likely users ip
 $noReferer = empty($_SERVER['HTTP_REFERER']);
 if(in_array($userIP,$banned) or $noReferer) {
   include_once('fakepage.php');
 } else {
   include_once('realpage.php');
 }
