Question

I’m new to this site, I have been coding a script to block certain IPs from a website, the thing is, it all works with the first IP in the column, say for example the database looks like this:

http://gyazo.com/290bc2b9ef77d5b985ddd675ba0c08d1

Then only the first IP, in this case 86.70.*. would be redirected to the banned page,
If someone could please help me get my php script working:

<?php 
mysql_connect("localhost", "root", "password") or die(mysql_error());  
mysql_select_db("bans") or die(mysql_error());  
$query = mysql_query("SELECT * FROM `database`"); 
$row = mysql_fetch_array($query); 
$ip = $_SERVER['REMOTE_ADDR']; //Gets the users IP adress

$deny = array( $row[ip]); 
if (in_array ($_SERVER['REMOTE_ADDR'], $deny)) {
   header("Location: http://gabbo.org.uk/banned.php"); //What page shall the bans be sent to?
   exit(); 
}?>

I would be very grateful!

Small change in your logic.

<?php 
    mysql_connect("localhost", "root", "password") or die(mysql_error());  
    mysql_select_db("bans") or die(mysql_error());
    $ip = $_SERVER['REMOTE_ADDR'];

    # Full Text Attempt
    $query = mysql_query("SELECT `IP` FROM `database` WHERE `IP` = '$ip'");
    # Wild Card Attempt
    $query = mysql_query("SELECT `IP` FROM `database` WHERE `IP` LIKE '%$ip%'");
    # Use any one query from the above!

    if (mysql_num_rows($query) > 0)
    {
        header("Location: http://gabbo.org.uk/banned.php");
        die();
    }
?>

Working

When a user with an IP Address of 192.168.1.1 attempts to access your page and your ban list of MySQL has it, it surely returns some rows, which is greater than 1. That way, the header gives a 301 Permanent Redirection to the browser to the banned page.
