PHP ban IP

[dezkit]

is there a way so that if the ip is 12.123.123.12 that it states a reason

 

<?php
$banned_ip = array();
$banned_ip[] = '12.123.123.12';
$banned_ip[] = '';
$banned_ip[] = '';
foreach($banned_ip as $banned) { 
    $ip = $_SERVER['REMOTE_ADDR'];
    if($ip == $banned){ 
        echo "<br><br><br><br><br><br><br><br><center>
<font size='+2'>You have been banned from this site for ??????.</font>
<br>For further information about your ban, please email us at [email protected]
and remember to include your IP Address
<br><br>Your IP address is ";
        echo $_SERVER['REMOTE_ADDR'];
        exit(); 
    } 
} 
?>

you can't ban by IP because the IP is not a valid resource to identify a single user.

 

You can only "allow" by IP if you know of a static source you wish to allow

wait so i cant do something like this?

 

if ($banned_ip[]=="12.123.123.12")
  {
  echo "Spamming"; 
  }

Cooldude isn't saying the code isn't possible, he's saying that it's not the best way to do it because it can be easily bypassed.

[dezkit]

ohh, im a beginner anyways... so i dont care if it can be bypassed can any of you create a code lol

[p2grace]

What does the code you have do?  Just glancing over it quick it looks accurate.

[dezkit]

i dont think you guys get what im saying 

 

i am saying that if the person on the computer has a ip banned from the site, so it echo's a reason why he was banned

 

like

 

    if($ip == $banned){

        echo "spamming";

        exit();

    }

}

 

 

or something

We get what you're saying, what I'm asking is what's wrong with the way you were doing it.  Create either a db table of banned ip addresses, or an array in a php page.  Check if the current ip address is either in that db table or in the array, if it is display an error.  Where are you confused?

[dezkit]

kk i choose the php array, now what do i do. lol

[p2grace]

Try this:

 

<?php
// Array of ip addresses
$blocked = array("12.123.123.12","1.1.1.1"); // keep adding ip addresses by comma. 1.1.1.1 is an example, feel free to remove it

// Grab users ip address
$ip = $_SERVER['REMOTE_ADDR'];

// Check if ip is supposed to be blocked
if(in_array($ip,$blocked)){
  echo "Spam";
  die();
}

?>

 

Something like that should work

[dezkit]

thanks for the code, but one problem... i want different reasons for different ips

[dezkit]

nevermind, i got it thanks alot!

 

<?php

$spam = array("xxxxx","xxxxx");
$other = array("xxxxx","xxxxx");

$ip = $_SERVER['REMOTE_ADDR'];

if(in_array($ip,$spam)){
  echo "Spam";
  die();
}
if(in_array($ip,$other)){
  echo "Other";
  die();
}

?>

No I'm saying innocent people will get banned in your system

[p2grace]

You mean because of isp dynamic ip releases?
