Check PageRank Through XML - php

Question

I've searched this website and googled alot but unfortunately didn't find any real answer so please pardon me if it doesn't makes sense.
I'm using PHP to check page rank of a given URL, but it sometimes show error due to busy google website (http://toolbarqueries.google.com) The error it shows is;
Is there any way I can check page rank through either XML or even PHP with a better solution, which doesn't show any error like that?
Please help!

Answer 1

I've searched and find a great solution. try this:
class GooglePageRankChecker {
// Track the instance
private static $instance;
// Constructor
function getRank($page) {
// Create the instance, if one isn't created yet
if(!isset(self::$instance)) {
self::$instance = new self();
}
// Return the result
return self::$instance->check($page);
}
// Convert string to a number
function stringToNumber($string,$check,$magic) {
$int32 = 4294967296; // 2^32
$length = strlen($string);
for ($i = 0; $i < $length; $i++) {
$check *= $magic;
//If the float is beyond the boundaries of integer (usually +/- 2.15e+9 = 2^31),
// the result of converting to integer is undefined
// refer to http://www.php.net/manual/en/language.types.integer.php
if($check >= $int32) {
$check = ($check - $int32 * (int) ($check / $int32));
//if the check less than -2^31
$check = ($check < -($int32 / 2)) ? ($check + $int32) : $check;
}
$check += ord($string{$i});
}
return $check;
}
// Create a url hash
function createHash($string) {
$check1 = $this->stringToNumber($string, 0x1505, 0x21);
$check2 = $this->stringToNumber($string, 0, 0x1003F);
$factor = 4;
$halfFactor = $factor/2;
$check1 >>= $halfFactor;
$check1 = (($check1 >> $factor) & 0x3FFFFC0 ) | ($check1 & 0x3F);
$check1 = (($check1 >> $factor) & 0x3FFC00 ) | ($check1 & 0x3FF);
$check1 = (($check1 >> $factor) & 0x3C000 ) | ($check1 & 0x3FFF);
$calc1 = (((($check1 & 0x3C0) << $factor) | ($check1 & 0x3C)) << $halfFactor ) | ($check2 & 0xF0F );
$calc2 = (((($check1 & 0xFFFFC000) << $factor) | ($check1 & 0x3C00)) << 0xA) | ($check2 & 0xF0F0000 );
return ($calc1 | $calc2);
}
// Create checksum for hash
function checkHash($hashNumber)
{
$check = 0;
$flag = 0;
$hashString = sprintf('%u', $hashNumber) ;
$length = strlen($hashString);
for ($i = $length - 1; $i >= 0; $i --) {
$r = $hashString{$i};
if(1 === ($flag % 2)) {
$r += $r;
$r = (int)($r / 10) + ($r % 10);
}
$check += $r;
$flag ++;
}
$check %= 10;
if(0 !== $check) {
$check = 10 - $check;
if(1 === ($flag % 2) ) {
if(1 === ($check % 2)) {
$check += 9;
}
$check >>= 1;
}
}
return '7'.$check.$hashString;
}
function check($page) {
// Open a socket to the toolbarqueries address, used by Google Toolbar
$socket = fsockopen("toolbarqueries.google.com", 80, $errno, $errstr, 30);
// If a connection can be established
if($socket) {
// Prep socket headers
$out = "GET /tbr?client=navclient-auto&ch=".$this->checkHash($this->createHash($page)).
"&features=Rank&q=info:".$page."&num=100&filter=0 HTTP/1.1\r\n";
$out .= "Host: toolbarqueries.google.com\r\n";
$out .= "User-Agent: Mozilla/4.0 (compatible; GoogleToolbar 2.0.114-big; Windows XP 5.1)\r\n";
$out .= "Connection: Close\r\n\r\n";
// Write settings to the socket
fwrite($socket, $out);
// When a response is received...
$result = "";
while(!feof($socket)) {
$data = fgets($socket, 128);
$pos = strpos($data, "Rank_");
if($pos !== false){
$pagerank = substr($data, $pos + 9);
$result += $pagerank;
}
}
// Close the connection
fclose($socket);
// Return the rank!
return $result;
}
}
}
Now where you want to check the PR, use this code $some_var = GooglePageRankChecker::getRank("http://khanqah-daruslam.com");
Replace URL to yours (or any custom URL)

Try SEOstats: https://github.com/eyecatchup/SEOstats
SEOstats is a powerful open source PHP library to request a bunch of
SEO relevant metrics such as detailed backlink analyses, keyword and
traffic statistics, website trends, page authority, the Google
Pagerank, the Alexa Trafficrank and much more.

Thanks but I already saw this and do not want to use any heavy library. I want a light weight PHP or XML code. Thanks anyway!
Actually you don't need to use the full library. SEOstats' Google PageRank method uses a standalone class that can be used as follows:
<?php
$url = 'http://somedomain.com/';
$pr = new GTB_PageRank($url);
$rank = $pr->getPageRank();
printf("The Google Pagerank of %s is %s.", $url, $rank);
The nice thing about this class, as I think, is that it supports all existing PageRank hashing algorithms (awesome, jenkins, jenkins2 and IE) and has some advanced features built in, such as suggested Toolbar-TLD and more.
