Alexa script is for increasing Alexa rank. Basically what it does is make
Alexa think that all the visitors to your site have the toolbar
installed. I just installed it in my sites tonight so I'll keep you
updated on how it works. I welcome any comments.

Code:
The Alexa toolbar itself generates a standard HTTP GET request. We can do the same by inserting a <IMG> tag with the resulting url as the source. Alexa actually returns XML markup as a response, but the contents are irrelevent for this purpose; we just want to trigger the logic.There are a bunch of query values in the URL; some are obvious, others... not so much.The keys to getting this to work is to start page generation with:----------------------session_start();----------------------If your using persistant sessions, you probably already got this.Next, create a new function somewhere in your code; if you have a global functions file, it'd probably go there. otherwise, you can put it right below the session_start() value above.----------------------function alexa() {$domain = "http://data.alexa.com";$keylength = 14; // the resulting length of the keyid. 14 and 15 were seen in the wild.// session_start() must have already been set. If so, this will ensure that each visitor maintains the same keyid throughout the entire visit.if (isset($_SESSION['alexa_keyid'])) {$keyid = $_SESSION['alexa_keyid'];} else {$keyid = substr(str_shuffle("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"),0,$keylength);$_SESSION['alexa_keyid'] = $keyid;}$cli = "10"; // ???$dat = "snba"; // ???$ver = "7.2"; // version number of toolbar?$cdt = "alx_vw"; // ???$wid = rand(0,32767); // appears to be a random integer initiated when the browser starts.$act = "00000000000"; // ???$ssarray = array ("800x800", "1024x768", "1280x768", "1280x800","1280x1024", "1600x1200", "1680x1050", "1920x1200");shuffle($ssarray);$ss = $ssarray[0]; // browser screensize. Resulting value is chosen at random from an array of values.$bw = "1523"; // bandwidth? probably used in calculating metrics related to visitor connection speeds (noted values are close to common// connection speeds like 768k, 1mb, 1.5mb, etc.)$t = "0"; // ???$ttl = rand(200,1000); // time-to-live? probably used in calculating average load times$vis = "1"; // ???$rq = rand(15,80); // appears to increment with each toolbar request$url = "http://<<<PUT YOUR DOMAIN HERE>>>/";$params="/data/".$keyid."?cli=".$cli."&dat=".$dat."&ver=".$ver."&cdt=".$cdt."&wid=".$wid."&act=".$act."&ss=".$ss."&bw=".$bw."&t=".$t."&ttl=".$ttl."&vis=".$vis."&rq=".$rq."&url=".$url;return $domain.$params;}---------------------Finally, insert somewhere on your page the following:---------------------<? echo "<img src='".alexa()."' height='0' width='0'>"; ?>---------------------That will trigger the actual event.Somebody else can probably clean and extend this code up better than I. This was a quick hack-togeather in about 30 minutes. If i'm on to something, it could also warrant a better explanation.
