Bandwidth Limit User

- by user45611

Hello, i'm saxtor i would like to know how to limit users bandwidth for 10gb per day however i dont want to limit them by ipaddress because if they where to go to an internet cafe the users at the cafe will be restricted with that quota, i need to log them via sockets, example the user request to download a file from http://localhost with there username and password, when they download the file sql will update there bandwidth they used, i have a script here but its not working my buffer doesnt work that rate when a user uses multiple connections thanks for the help!. /** * @author saxtor if you can improve this code email me @saxtorinc.com * @copyright 2010 / /* * CREATE TABLE IF NOT EXISTS max_traffic ( id int(255) NOT NULL AUTO_INCREMENT, limit int(255) NOT NULL, PRIMARY KEY (id) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=0 ; */ //SQL Connection [this is hackable for testing] date_default_timezone_set("America/Guyana"); mysql_connect("localhost", "root", "") or die(mysql_error()); mysql_select_db("Quota") or die(mysql_error()); function quota($id) { $result = mysql_query("SELECT `limit` FROM max_traffic WHERE id='$id' ") or die(error_log(mysql_error()));; $row = mysql_fetch_array($result); return $row[0]; } function update_quota($id,$value) { $result = mysql_query("UPDATE `max_traffic` SET `limit`='$value' WHERE id='$id'") or die(mysql_error()); return $value; } if ( quota(1) != 0) $limit = quota(1); else $limit = 0; $multipart = false; //was a part of the file requested?
