Description
What is Google PageRank?

PageRank is a family of algorithms for assigning numerical weightings
to hyperlinked documents (or web pages) indexed by a search engine.
Its properties are much discussed by search engine optimization (SEO)
experts. The PageRank system is used by the popular search engine
Google to help determine a page's relevance or importance.

As Google puts it:

> PageRank relies on the uniquely democratic nature of the web by
> using its vast link structure as an indicator of an individual
> page's value. Google interprets a link from page A to page B as
> a vote, by page A, for page B. But Google looks at more than the
> sheer volume of votes, or links a page receives; it also analyzes
> the page that casts the vote. Votes cast by pages that are
> themselves "important" weigh more heavily and help to make other
> pages "important."

This class will calculate and return the Google PageRank of the
specified input URL as integer. Class was build based on Raistlin
Majere's google_pagerank function

Change Log:

  2008-01-24  * Hash calculation functions updated because of
                miscalculation based on php versions. 
                (algorithm updated based on a anonymous source
                code which supposed to be found at
                http://pagerank.gamesaga.net but not exists 
                any more.)
  2005-12-07  * Small bug removed (dies when caching disabled)
  2005-11-24  * Added user-agent support
              * Class selects random google hostnames in
                order to prevent abuse. (You may define extra
                google hostnames)
              * Class now first tries cURL, fsockopen() and
                file_get_contents() to connect google servers.
              * Added caching option to class. Results now can be
                cached to flat files in order to prevent abuse and
                increase performance.
              * Cache files are stored in seperate directories for
                performance issues.

  2005-11-04  * Initial version released


Ex:
$gpr = new GooglePR();
//$gpr->debug=true; //Uncomment this line to debug query process
echo $gpr->GetPR("http://www.progen.com.tr");

//Uncomment following line to view debug results
//echo "<pre>";print_r($gpr->debugResult);echo "</pre>";

Google search result pages has become one of the most important sources of visitors to content Web sites.

To maximize the number of site visitors, it is important that the pages of the site appear first in as many Google search result pages as possible.

The Google search results are sorted by a factor named page rank. Higher ranked pages have greater chances of appearing first in Google search result pages.

The Google page rank is computed according to a patented algorithm that takes in account incoming and outgoing links of the page.

The exact page rank formula and factors that affect its value are not publically known. However, the rank of a page is informed by the Google Toolbar from queries that it performs to the Google servers.

This class can query Google servers and retrieve the rank of a given page. This way anybody can determine the page rank without needing to install the Google Toolbar.

As for the last year the big buzz has been on the Google PR formula and the new science of hacking it, I have spent some time myself with it. To discover that although it’s nice to see the green bar filling up the white space in the ranking box, it does not say much about your keyword relevance.
