PHP Code Get Alexa Rank and Site Linking

May-25-2014 in PHP No comments

In this post, I will explain how to use PHP code to get Alexa rank and site linking of your blog or website using a simple PHP script

How to Find Alexa Rank?

The PHP code to get Alexa rank and sites linking in is pretty simple and straightforward:

The URL to get the Alexa rank and some other useful fields in XML format is:

http://data.alexa.com/data?cli=10&dat=snbamz&url=www.your-domain.com

1	http://data.alexa.com/data?cli=10&dat=snbamz&url=www.your-domain.com

Note that it has several important fields like popularity, DMOZ listings, the countries in which the site is most popular etc.

To parse this XML file either you can use regular expression match or use initialize curl with given url. here i am doing this with curl_init()

<?php
function initialize_curl($url) {
        if(function_exists('curl_init')) {
    $ch = curl_init($url); // initialize curl with given url
    curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // add useragent
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // write the response to a variable
    if((ini_get('open_basedir') == '') && (ini_get('safe_mode') == 'Off')) {
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects if any
    }
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); // max. seconds to execute
    curl_setopt($ch, CURLOPT_FAILONERROR, 1); // stop when it encounters an error
    return @curl_exec($ch);
        }
        else {
    return @file_get_contents($url);
        }
}
?>

<?php

function initialize_curl($url) {

if(function_exists('curl_init')) {

$ch = curl_init($url); // initialize curl with given url

curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // add useragent

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // write the response to a variable

if((ini_get('open_basedir') == '') && (ini_get('safe_mode') == 'Off')) {

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects if any

}

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); // max. seconds to execute

curl_setopt($ch, CURLOPT_FAILONERROR, 1); // stop when it encounters an error

return @curl_exec($ch);

}

else {

return @file_get_contents($url);

}
