$register_globals = (bool) ini_get('register_gobals');
if ($register_globals) $vis_ip = getenv(REMOTE_ADDR);
else $vis_ip = $_SERVER['REMOTE_ADDR'];

function recordData($vis_ip,$ipLog,$goHere)
{ 
    $log=fopen("$ipLog", "a+"); 
    fputs ($log,$vis_ip."][".time()."\n"); 
    fclose($log); 
 
    // The below header function was causing errors in apache 
    //so I changed it to echo the script tag. 
    //Header ("Location: $goHere"); exit(0);  
    echo "<script>location.replace('$goHere')</script>"; exit(0);
} 
function checkLog($vis_ip,$ipLog,$timeout) 
{
    global $valid; $ip=$vis_ip;
    $data=file("$ipLog"); $now=time();

foreach ($data as $record) 
    {
        $subdata=explode("][",$record);
        if ($now < ($subdata[1]+3600*$timeout) && $ip == $subdata[0]) 
        {
            $valid=0; echo "You have been banned from accessing this page. Try again in $timeout hours.";
            break;
