PHP Code to Grab Alexa Traffic Ranking

Here is a php code that lets you retrieve a website’s alexa ranking, useful in web applications that measure importance of webpages (such as bespoke link popularity tools).

For this code snippet to work CURL library for php needs to be enabled on your server.

Code:

 <?php
 function alexaRank($domain)
 {
$ch = curl_init(‘http://alexa.com/data/details/traffic_details?url=’.$domain);
    curl_setopt($ch, CURLOPT_TIMEOUT, 50);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, ”Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1″);
    $curl_ret = curl_exec($ch);
    curl_close($ch);
    
    $curl_ret = explode(‘Visit http://aws.amazon.com/awis for more information about the Alexa Web Information Service.–>’, $curl_ret);
    $curl_ret = array_shift(explode(‘<br’,$curl_ret[1]));
    $ret = ”;
    $ignore = false;
    for($i=0;$i<strlen($curl_ret);$i++)
    {
  if ( is_numeric($curl_ret{$i}) && !$ignore )
   $ret .= $curl_ret{$i};
  else if ( $curl_ret{$i} == ’<’ )
   $ignore = true;
  else if ( $curl_ret{$i} == ’>’ )
   $ignore = false;
}
    return (int)$ret;
 }

To display the Alexa ranking, use the following code :

echo alexaRank(‘site.com’);
