This is a small script can be used to redirect banned ip address users from your website, what it does exactly is calls the function “ipbanCheck” checks the database “ipban” for a matching IP Addresses of the current users IP Address then redirects them via javascript to = http://www.google.co.uk/search?q=GTFO 
Database Setup:
1) log into phpMyAdmin, select the database you want the table built into.
2) select “SQL” from the tab menu, run the below.
SQL code:
CREATE TABLE ipban ( ID int(12) NOT NULL auto_increment, IP varchar(25) NOT NULL default '', PRIMARY KEY (ID) ) TYPE=MyISAM;
3) should output “executed successfully” etc. now select the table “ipban” then select “Insert” from tab menu now enter the IP Address your want to BAN in the field “IP”.
Usage:
Reason why i’m out putting the echo’s with outs like: “&conn=YES&IP=$ip” is for Flash loadVars integration. To use this function “ipbanCheck” just call it like so;
require_once 'ipban.php'; //file path to the file
ipbanCheck(); //check function
Example
http://3l3373.com/dl/tutorials/ipBan/check.php – You should see an output of “&conn=YES&IP=93.97.40.201ban=NO&” unless You have been BANNED
