Redirection of specific IP address to specific page in PHP

Question

I have used below code to redirect specific IP address to specific page/website. It is working fine in Google Chrome but in Firefox and Internet Explorer, I am getting Error : "The page isn't redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete."

Code:

<?php

$visitor = $_SERVER['REMOTE_ADDR'];

if(preg_match("/192.168.1.187/",$visitor)) { 
header('Location: http://yahoo.com'); 
} 

else { 
header('Location: http://www.google.com'); 

}; 
?>

Answer 1

Seems like there is an endless redirect to the URL , Clear your cookies once and try adding HTTPS before the URLs and give a shot.

Also add an exit or die after your header function. That will do.

Like..

<?php

$visitor = $_SERVER['REMOTE_ADDR'];

if(preg_match("/192.168.1.187/",$visitor)) { 
header('Location: https://yahoo.com');
exit; //<-- Here 
} 

else { 
header('Location: https://www.google.com'); 
exit; //<-- Here
}; 
?>

Tested the script in Nightly 29 (Firefox). I didnt get an error at all. But you should add exit behind each header so the script interrupts. And maybe you should add www in front of the yahoo homepage.
