PHP ban IP range script

[DJMaze]

$ip_from = "192.168.0.0";

vs

$ip_from = "19.216.80.0";

What do both result in after you did str_replace(".","",$ip_from) in both?

And no, don't ask about IPv6 routines!!!!

Ahh, didn't think so far.

How about?

PHP Code:

$ip = $_SERVER['REMOTE_ADDR'];
$ip = explode(".",$ip);

$ip_from = "192.168.0.0";
$ip_to = "192.168.255.255";

$ip_from = explode(".",$ip_from);
$ip_to = explode(".",$ip_to);

$a = 0;
while($a <= 3) {
if ($ip[$a] < $ip[$a] || $ip[$a] > $ip_to[$a]) { die("Denied"); }
$a++;
}

  // make sure this is an array before we use foreach
  if (is_array($ip_array)) {

    foreach ($ip_array as $ip) {

      // first test if there is a match, then test if the match starts at the beginning
      if (strstr($ip_to_match, $ip) && strpos($ip_to_match, $ip)==0) {
        return true;
      }
    }
  }

  return false;
}

$ban_array = array(
  '216.47.55.141',
  '72.47.147',
  '74.171',
  '58'
);

if (checkIP($_SERVER['REMOTE_ADDR'], $ban_array)) {
  echo "This page is not accessible.";
  exit;
}
?>

I'm sorry, this old thread i reply on this time, cause i really need help. So, the code above is work perfectly for me, but there's one option that i looking for. And cause i'm newbie, so can't figure it. I wanna the result is look like :

You ip address xxx.xxx.xxx. has been banned from this site !

So, in the echo syntax i put $ip, so it look like below:

You ip address $ip has been banned from this site !

but it doesn't work, i also change the $ip on message above with $ban_array, and $ip_to_match too...but still doesn't work.

so, what's the syntax i must add into the message? please tell me!

$_server['remote_addr']

@redhead

thanks but i got error:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/ibenk/public_html/ban.php on line 18

[redhead]

It's case sensitive and should be: $_SERVER['REMOTE_ADDR']

[ibenk]

sorry for the late reply,

i still got error, and now the error appear in line 28, exactly in :

echo "Your ip address $_SERVER['REMOTE_ADDR'] has been banned from this site !";

I know this is a little old...well a year old but shouldn't it be

PHP Code:

echo "Your IP Address " . $_SERVER['REMOTE_ADDR'] . " has been banned from this site !"; 


That should work, but do not forget to note the dots inbetween....
