Auto ban ip from file

[Tko_1]

Okay so i have a page when it is visted stores there ip to file and bans there ip access to a differant page. Problem i have is it will only ban the last visted ip, which i want to ban all ip's in the file.

page1 which is visted and sotes ip in blocked_ips.php

<?
$ipaddress = "\r\n" . $_SERVER['REMOTE_ADDR'];

$file = 'blocked_ips.php';

$fp = fopen($file, 'a');

fwrite($fp, $ipaddress);

fclose($fp);
?> 

page2 which denys access to the ip

<?php
$deny_ips = file('ban/blocked_ips.php');

// read user ip address:
$ip = isset($_SERVER['REMOTE_ADDR']) ? trim($_SERVER['REMOTE_ADDR']) : '';

// search current IP in $deny_ips array
if (($i = array_search($ip, $deny_ips)) !== FALSE){

// user is blocked:
print "<CENTER> YOU HAVE BEEN BANNED ! </CENTER>";
exit;
}

// If we reach this section, the IP address is valid

?>
<?php

so again the idea is to block/ban all ips in the blocked_ips.php, any help would be greatly appreciated.

thank you

Hi,

I think that your script works but you should do tests in different machines to know if every time the ip adress has been blocked or not.

thanks akmozo . well like i said it does log the ip but will not block all ips just the last one that was logged. i have done tests from differant pcs on this and it will not ban all the ips from the file.

any ideas?

Try with in_array.

Hi again,

Try this :

<?php

    $ips_file_path = 'ips.php';   

    $my_ip = $_SERVER['REMOTE_ADDR'];

    ///////////////// use array /////////////////

    $ips_list = file($ips_file_path);

    foreach (array_values($ips_list) AS $ip){
        if (trim($ip) == $my_ip){
            print "<CENTER> YOU HAVE BEEN BANNED ! </CENTER>";
            exit;
        }
    } 
    echo 'Authorized ip !';        

    ///////////////// use string /////////////////

    $ips = file_get_contents($ips_file_path);

    if(strstr($ips, $my_ip)){
        print "<CENTER> YOU HAVE BEEN BANNED ! </CENTER>";    
    }else{
        echo 'Authorized ip !';
    }

?>

// Close the .htaccess file - all done.

You can try this code for band all ip adress.

[Biiim]

if (($i = array_search($ip, $deny_ips)) !== FALSE){
// user is blocked:
print "<CENTER> YOU HAVE BEEN BANNED ! </CENTER>";
exit;
}

Not sure if that will work, makes more sense to me like this:

if (array_search($ip, $deny_ips) !== FALSE){
// user is blocked:
print "<CENTER> YOU HAVE BEEN BANNED ! </CENTER>";
exit;
}

I would database it for better control, you could ban for a set time etc. Likely faster once the file starts to get big as well

Also check the data in the array $deny_ips: http://uk3.php.net/manual/en/function.file.php

according the that file() will include the line breaks into the value so that "12.34.56.78" != "12.34.56.78\r\n";

try file('ban/blocked_ips.php',FILE_IGNORE_NEW_LINES);
