How do you ban people based on IP addresses

How do you redirect people based on IP addresses using PHP if they cannot enter a password and redirect people that are not banned straight to a home page?

 

Their IP address, if they are not using a proxy, is in $_SERVER['REMOTE_ADDR'].

 

Something like this:

$ip = $_SERVER['REMOTE_ADDR'];
$query = mysql_query("SELECT * FROM banned_ips WHERE ip = '$ip'");

if( mysql_num_rows($query) == 0 )
{
    header("Location: http://example.com/index.php");
}
else
{
    die("Sorry, you're banned!");
}

PHP:

You would have to have a table with banned IP's in them, of course. Hope that helps.

or..

<?php
//banned ips
$bannedips = array("123.2334234.23", "34345.24354.34");

if(in_array($_SERVER['REMOTE_ADDR'], $bannedips)){

echo "Your banned";

} else {

header("Location: http://example.com/index.php");

}
?>
