Simple function to determine if a visitor is an agent or not

function isbot($agent="")
    {
    //Handfull of Robots
    $bot_array      =array("jeevesteoma",
                                   "msnbot",
                                   "slurp",
                                   "jeevestemoa",
                                   "gulper",
                                   "googlebot",
                                   "linkwalker",
                                   "validator",
                                   "webaltbot",
                                   "wget");
    //no agent given => read from globals
    if ($agent=="")
        {
        @$agent=$_SERVER["HTTP_USER_AGENT"];
        }
    //replace all but alpha
    $agent=strtolower(preg_replace("/[^a-zA-Z _]*/","",$agent));
    //check für intersections
    return((BOOL)count(array_intersect(explode(" ",$agent),$bot_array)));
    }

I think it is very important to note that PHP will automatically replace dots ('.') AND spaces (' ') with underscores ('_') in any incoming POST or GET (or REQUEST) variables.
