GOOGLE|PR Value | page | show | page
Google itself provides an interface for querying the PageRank value of a specified URL, and knowing this interface makes it easy to write a script to implement this function on the page without relying on Google toolbar to make inquiries. This article provides a PR query interface implemented in PHP.
It's easy to use, just where you need it.
〈?php
Include_once ("./pr.inc.php");
echo GETPR ($urlToQuery);
?〉
The value of the PageRank of the specified URL can be displayed. Know this number on the basis of the simulation of Google Toolbar above the graphical PR display is not difficult. In fact, the implementation of the principle is very simple, is to pass specific query parameters to Google's search engine, and then crawl the returned page content.
