My simple spam detector function lol

[Ponick]

it can detect 3 part domain name and it wont bother in normal text

function check_domain($text)
    {
    
    $check_domain_in_string = "^([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,5})$";
    /*
    you can use instead,if you only wanted to detect known domain.
    $check_domain_in_string = "^([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.com|edu|co.uk|gov|biz|tv|info|net|co.cc|in$";
    */
        if (ereg($check_domain_in_string, $text)) 
    {
        return true;
    break;    
    }                     
    return false;
    }

hehehe people hardly write http or www in normal text and i said its a symple fuction lol detect only valid domain from given text,

change

$check_domain_in_string = "^([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,5})$"; 

to

$check_domain_in_string = "^([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([a-zA-Z0-9]{2,})$"; 

then it can detect your ip domain :p

Added after 3 minutes:

i cud always write dot com pmpl jp.

You gave me an idea.
Why not take all the domains in the file, it would not be large and the certainly there somewhere on the net ready, loop through all and preg_match them and if there is a link, to stop entry and throw a notice, or simply search and replace parts matched with preg_replace.
