Checking IP's against spammer database

There is a good free RBL that checks users against a database of known forum spammers. You can check a users IP against it before allowing them to do anything on your site. Here is some example PHP code:

Code:
function blacklisted($ip) 
{
    $dnsbl_check=array("dnsbl.tornevall.org");

    if($ip){
        $rip=implode('.',array_reverse(explode(".",$ip)));
        foreach($dnsbl_check as $val){
            if(checkdnsrr($rip.'.'.$val.'.','A'))
                return $rip.'.'.$val;
        }
    }

    return false;
}
Basically just pass the IP to this function and if it comes back as true, then the IP is listed.

Enjoy!

OK maybe I am not understanding how this works

the above code which starts with

function blacklisted

I thought that the code would check with the SPAM IP site?

so I was wondering where the code would be placed

my apologies in advance if I have the wrong end of the stick

Thanks

If you have some PHP code, and you want to check to see if an IP address is of a known spammer, put the function in the first post of this thread into your PHP script. WHERE exactly I cannot tell you as that is different in every script.

Then you just pass the IP to the function and it will tell you true or false:

Code:
if (blacklisted('123.123.111.123'))
{
## This IP is blacklisted!
}
If you think you can just plug this into any script without any programming knowledge, then I would say no. You have to have some understanding how the code is working. This is a generic function, not a specific one for a particular program.
