PHP4 script to get Alexa Traffic Rankings

[sacx13]

The primarly code was found on: http://www.checkurl.info

function Alexa($domain) {
    //define vars
    $return = 0;
    $serviceURL = 'http://awis.amazonaws.com/onca/xml';

    $service = "AlexaWebInfoService";
    $operation = "UrlInfo";
    $timestamp = gmdate("Y-m-d\TH:i:s.\\0\\0\\0\\Z", time()); // Timestamp format: yyyy-MM-dd'T'HH:mm:ss.SSS'Z'
    $signature = '';
    $secretAccessKey = 'YOUR SECRET KEY';
    $signature = urlencode(calculate_RFC2104HMAC($service.$operation.$timestamp,$secretAccessKey));
    $timestamp = urlencode($timestamp);

    // construct the query
    $q = '?Service='.$service
        .'&AWSAccessKeyId=YOUR PUBLIC KEY'
        .'&Operation='.$operation
        .'&ResponseGroup=Rank'
        .'&Url=www.'.$domain
        .'&Timestamp='.$timestamp
        .'&Signature='.$signature;

    // get the xml results
    $fetchURL = $serviceURL.$q;

    if(!$xml = @file_get_contents($fetchURL)) {
        $file = @file($fetchURL);
        $xml = implode("", $file);
    }
//    echo $xml;
    // if the result was invalid, meaning API key expired
    if(strstr('<IsValid>False</IsValid>', $xml)) {
        $xml = '<Rank>-1</Rank>';
    }

    // find the rank
    preg_match('/\<Rank\>(\d+)\<\/Rank\>/', $xml, $result);
    $return = $result[1];

    // return the results
    return "$return";
}

function calculate_RFC2104HMAC ($data, $key) {
    return base64_encode (
        pack("H*", sha1((str_pad($key, 64, chr(0x00))
        ^(str_repeat(chr(0x5c), 64))) .
        pack("H*", sha1((str_pad($key, 64, chr(0x00))
        ^(str_repeat(chr(0x36), 64))) . $data))))
     );
}

How to use:

 $apr=Alexa("namepros.com");
 echo "Alexa Rank for namepros.com is: ".$apr."<br>";

What is the secret key?

What is the secret key?

AWS developer's key - https://aws-portal.amazon.com/gp/aws/developer/registration/index.html

Guess I'll have to get me one of those.

If people need a simple solution, you can query:

http://www.stscac.com/dev/alexa/?url=x

x = http://www.domain.com or http://domain.com or domain.com

For those of you who want the rank without having to worry about any code or the bulky alexa site.

That's cool you set this up. Newbie developers could use file_get_contents with that URL if they wanted a checker or something. Here's an example for PHP-illiterate folks of how to use this in their scripts.

<?
if (isset($_POST['submit'])) {
$str = file_get_contents("http://www.stscac.com/dev/alexa/?url=".$_POST['url']);
$str = trim($str);
echo "Rating for ".$_POST['url']." is ".$str;
}
else
{
?>
<form name="alexarate" method="post" action="<?=$_SERVER['PHP_SELF']; ?>">
Get Alexa Rating For:
<input type="text" name="url" value="http://"> <input type="submit" name="submit" value="Get Rating!">
</form>
<?
}
?>

there are also versions that doesn't require AWS developer's key

 

[webbist101]

I'm sure you can develop your own API that communicates with the Alexa site directly. I might script up something for the users at NP when I'm not so tired

Yep :D

That's the reason I did it. I remember when I was a rather newbie when it came to web development, and I do remember people helping out and helping me learn different functions through examples.

I figure that some people will not be able to understand the code in the first example, I'll make it a little more bearable for them.

I'm not asking for anything at this time, but just let me know what site you're pulling the data to so I can keep track.

Yeah, I can see this becoming a problem. However, I doubt many sites recieving any serious traffic would still use your system, as they would be on a high enough budget to afford developers to do this theirselves.

I figured this much. But for those who do use it, just drop me a line.
