PHP IP Ban/Redirect. Can you help with my script?

Im in need of a little help with my php script if anyone has a bit of time. Simply put what i'm attempting to do is have the php script look at every person's IP as they come to my page. If their IP is in the banned_ip list i'm wanting to redirect that person to the first URL ( http://www.yahoo.com ).
If their IP is not in the list I want to redirect these people to the second URL in the script ( http://www.google.com ).

It's basically a php IP ban/redirect script. I have tried it on my host the way it is written and added my own IP to the banned list and it kept sending me to the 2nd URL when it should have sent me to the 1st. I'm lost. I'm a complete PHP newb guys so please keep the laughing and rude comments to a minimum, lol.

Anyways i'd appreciate any and all help I can get. Below is my code.

<?php 
$banned_ip = array(); 
$banned_ip[] = '204.96.148.3'; 
$banned_ip[] = '205.162.217.141'; 
$banned_ip[] = '209.62.82.14'; 
$banned_ip[] = '24.7.101.103'; 
$banned_ip[] = '65.31.130.2'; 
$banned_ip[] = '68.168.78.226'; 
$banned_ip[] = '68.205.75.110'; 
$banned_ip[] = '69.36.158.35'; 
$banned_ip[] = '70.173.198.69'; 
$banned_ip[] = '70.97.122.18'; 
$banned_ip[] = '71.189.157.53'; 
$banned_ip[] = '71.230.54.244'; 
$banned_ip[] = '74.52.245.146'; 
$banned_ip[] = '76.90.3.205'; 
$banned_ip[] = '24.20.251.76'; 
$banned_ip[] = '68.83.254.243'; 
$banned_ip[] = '69.2.27.10'; 

foreach($banned_ip as $banned) {  
    $ip = $_SERVER['REMOTE_ADDR']; 
    if($ip == $banned){  
        header("location: http://www.yahoo.com"); 
}
else
{
        header("location: http://www.google.com"); 
        exit();  
    }  
}  


?>  

Code (markup):

 

echo your IP in the PHP script and make sure you're using the right IP.

Furthermore, I'd do like like this:

if (in_array($_SERVER['REMOTE_ADDR'], $banned_ip))
{
    header('Location: http://yahoo.com');
    exit(); // This exit() is more important than the other
}
else
{
    header('Location: http://google.com');
    exit();
}

PHP:

It's way faster than the loop...

 

Thank you very much.
Any ideas about banninjg a range of IPs if I want to use th same script as well. Like if i wanted to ban 208.80.193.[1 - 255]

 

$banned_ip[] = '204.96.*.4'; 
$banned_ip[] = '205.162.217.141'; 
$banned_ip[] = '209.62.82.14'; 

function is_banned($ip)
{
	$pattern = str_replace(array('*', '.'), array('\d+', '\.'), $ip);
	return preg_match("~^{$pattern}$~", $_SERVER['REMOTE_ADDR']);
}

if (array_filter($banned_ip, 'is_banned'))
{
	echo 'Banned';
}
else
{
	echo 'Not banned';
}

PHP:

Use an asterisk wherever you want to allow the range.
