用PHP抓取Alexa信息

Question

I'm trying to receive information about Alexa Top Sites from a Contrie, and i would like to receive:

• Website Position;
• Website URL;

For the URL i'm getting already, but when i add tag for website position something isnt working, here's my code:

<?php

for ($z=0;$z<2;$z++) {
$html=file_get_contents('http://www.alexa.com/topsites/countries;'.$z.'/PT');
preg_match_all(
    '/<div class="count">.*?<\/div>.*?<a href="\/siteinfo\/.*?">(.*?)<\/a>/s',
    $html,
    $array, //array with sites
    PREG_SET_ORDER
);

for ($i=1;$i<count($array);$i++) {
    echo "<pre>"; print_r($array); echo "</pre>"; 
}
} 


?>

I'm getting this:

Array
(
[0] => Array
    (
        [0] => 
1



google.pt
        [1] => google.pt
    )

[1] => Array
    (
        [0] => 
2

Why not use the official API?

It costs $0.15 for 1,000 requests, and you''ll get nice XML readble by SimpleXML. As bonus - you won't violate the alexa terms of usage.
