[Tut] Super Simple php IP banning

[Mentor]

humm the in array is probably a better way of doing it, although i think your syntax has problems

<?php

  $b[] = '0.0.0.1';
  $b[] = '0.0.0.2';
  $b[] = '0.0.0.3';

if(in_array($_SERVER['REMOTE_ADDR'], $b)){
die("You're banned.");
}
?>

I think my syntax is fine.

This is how I'd do it.

Save this as Ban.php if you want.

<?php
//Ban.php
$ip1 = 'xxx.xxx.xxx.xxx';

$ip2 = 'xxx.xxx.xxx.xxx';

$ip3 = 'xxx.xxx.xxx.xxx';


if($_SERVER['HTTP_X_FORWARDED_FOR'] == $ip1||$_SERVER['HTTP_X_FORWARDED_FOR'] == $ip2||$_SERVER['HTTP_X_FORWARDED_FOR'] == $ip3) {
echo("Sorry your banned.");
}
?>

Then on your index page, to check if the IP is banned... Add this code anywhere, preferably at the top.

<?php
include("ban.php");
?>

Thats actualy quite a good idea? Since you dont need to worry about whether the public or proxie Ips are not the one you banned since it checks all "/

Meh, you could use another way of doing it If you have a MySQL database and not alot of tables you can make)

<?php
include("configurationofmysqldatabasewithareallylongunneededname.php");
$dynamite = mysql_fetch_array(mysql_query("SELECT `ip` FROM `bannageness` ORDER BY `ip` DESC"));
$explosion = explode(";", $dynamite["ip"]);
for($num = 0; $num < count($explosion); $num++)
{
    if($_SERVER["REMOTE_ADDR"] == "$explosion[$num]")
        {
            die("lol banned");
        }
}
?>

right, i have this problem

my ban.php is in a directory such as

1/2/3/4/5/6/7/8/9/ban.php


and if i put this incluede on my homepage

<?php
include("ban.php");
?>

it only reads the same directory as the files in. and when i try to put in the full url such as

http://www.bonxy.co.uk/1/2/3/4/5/6/7/8/9/ban.php it comes up with loads of error lines. anyone know how i can get around this problem ????

Why not also set a banned cookie and a session and make it check for that so if it has either of the 3 then your banned...?

Can clear cookies, sessions, and change my IP very easily.

I don't really think there is a decent way of banning someone!
