Php code help.
Hello again,

I'm trying to block ips using a php script (no .htaccess).

Code:
<?
if ($_SERVER['REMOTE_ADDR'] == "109.101.51.119") die();
?>

How can I make this to block the entire block -> 109.101.*.*

Found something while searching the web but the codes are too complex. I just wanna make it simple.

Also tried:

Code:
<?
if ($_SERVER['REMOTE_ADDR'] == "109.101.*.*") die();
?>

and it doesnt work.

Any tips? Thanks in advance.

Try:
Code:
if (preg_match('/^109\.101\.[^.]+\./', $_SERVER['REMOTE_ADDR'])) .....

EDIT: or simpler, try:
Code:
if (preg_match('/^109\.101\./', $_SERVER['REMOTE_ADDR'])) .....

Another approach...
PHP Code:
$remoteip = $_SERVER['REMOTE_ADDR'];
$bannedblock = "109.101.";

if (substr($remoteip, 0, strlen($bannedblock)) == $bannedblock) {
 die("Banned IP!");
}

Try, this works for exact matches as well as for wild card matches

Code:
<?php


// Array's of banned IP addresses
$bannedIP = array("127.0.0.1", "^99.88.77.*", "192.168.0.1", "^66.77.*.*");

// This is for exact matches of IP address in array
if(in_array($_SERVER['REMOTE_ADDR'],$bannedIP))
  {
     header("Location: http://www.google.com");
     exit();
 } 
else 
 {
     // This is for wild card matches
    foreach($bannedIP as $ip)
    {
          if(eregi($ip,$_SERVER['REMOTE_ADDR']))
          {
               header("Location: http://www.yahoo.com");
               exit();
          }
    }
}
?>

For example if array is

Code:
$bannedIP = array("127.0.0.1", "^99.88.77.*", "192.168.0.1", "^66.77.*.*");

it will redirect to google.com since its exact match

where as if array is

Code:
$bannedIP = array("127.0.0", "^99.88.77.*", "192.168.0.1", "^66.77.*.*");

it will redirect to yahoo.com since its wild card match

@Akshay: It seems to me the non-exact matches (and thus extended regex) need the dots to be escaped, no?
Code:
$bannedIP = array("127.0.0.1", "^99\.88\.77\..*", "192.168.0.1", "^66\.77\..*\..*");

or
Code:
$bannedIP = array("127.0.0.1", "^99\.88\.77\.", "192.168.0.1", "^66\.77\.");

Ashay's PHP code doe not use REGEX:

Code:
in_array()

searches haystack for needle using loose comparison unless strict is set.

See PHP: PHP type comparison tables - Manual

Update: Ah! I see later in the code Ashay uses eregi()....
