Redirect or Block PHP + mySQL

TsingTao

Hello PHP Gods...

As n00b, I am looking support for php development. Idea is to create simple PHP which looks user IP and checks database for match. If found the output would be deny of access with information of IP and IP owner, these two are available from database.

problem is that currently the block list is .txt format, and some of the IP owners have batch of IP number like xxx.xxx.215.10-xxx.xxx.215.214 these middle numbers should also be identified, some of the blocked ips are single type.

The Ip list is available from here:
http://methlabs.org/sync/guarding_all.p2p.zip
and it opens with any test editor.

If there is no match the user should be automatically redirected to site.

If anyone would have time for this or could support this....Thank you...

the basic idea, tweak as necessary:

if (strpos($_SERVER['REMOTE_ADDR'], '-') === true)
{
	$explode = explode('-', $_SERVER['REMOTE_ADDR']);
	foreach ($explode as $value)
	{
		if (in_array($value, $list_of_bad_ips)) {exit('sorry, your IP is bad');}
	}
}
else
{
	if (in_array($_SERVER['REMOTE_ADDR'], $list_of_bad_ips)) {exit('sorry, your IP is bad');}
}

Thank you mike,

Here is a sample of one line in the block.txt file.

bsa.org.il AP2P:209.238.113.75-209.238.113.77

all the entries are in same format, <name of the ip owner>:<ip start>-<ip end>

how do I separate the first name then the ip, if match would occur, the output or print to webpage would be <name of hte ip owner> from <ip> has no access to this site.

Here is the IP Block PHP Code solved by another forum, thank you all here.

<?php
  if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $clip = $_SERVER['HTTP_X_FORWARDED_FOR'];
  }
  elseif (isset($_SERVER['HTTP_VIA'])) {
    $clip = $_SERVER['HTTP_VIA'];
  }
  elseif (isset($_SERVER['REMOTE_ADDR'])) {
    $clip = $_SERVER['REMOTE_ADDR'];
  }
  else {
    $clip = "Unknown";
  }

$banned = file("ipout.txt", "r+");
$cbanned = count($banned);
function banit($clip,$banned,$cbanned){
for ($i = 0 ; $i < $cbanned ; $i++){
if ($clip==$banned[$i]){

echo '<html><head><title>Banned IP check</title>
</head><body><center><p><table width=550 border=0 cellspacing=0 cellpadding=10><tr><td>Your access has been denied</td></tr><tr><td></tr></table></body></html> ';
die();
 }
 }
}
banit($clip,$banned,$cbanned);
?>

So ipout.txt has all the blocked IPs in row format.
