Welcome to show the recipient's website PR

It's okay to think about a slightly cheap function. It shows the other party's pr on the welcome visitor interface. This can also be widely used in comments and User links, but it's too cheap, so I decided to show the visitor only. you can see the results. By the way, the url structure of the Googlepagerank API is as follows: toolbarqueries. google. c

You should have seen the results. By the way, please refer to a picture.

The API address structure of Google pagerank is as follows:

http://toolbarqueries.google.com.hk/tbr?client=navclient-auto&features=Rank&q=info:xiaohudie.net&ch=820909c8a

The value of the ch below is equivalent to a key, which requires php computation. However, during a local test, I found that the computation result is different from that on my website, at present, I do not know whether it is a PHP version or a Windows or LINUX issue. So let's give both calculation methods. If the first method does not call up the correct PR, replace it with the second one.
To query the PHP version, follow these steps:

The following code shows the visitor's website PR

Code 1

This is what I tested on my website. The operating system is LINUX and PHP version is 5.2.17.

 > 23) & 0x1FF) | $ hash <9;} return sprintf ("8% x", $ hash) ;}$ domain1 = $ _ COOKIE ["comment_author_url _". COOKIEHASH]; $ domain = substr ($ domain1, 7); // remove the http: // in front of the visitor's URL and keep only domain $ startUrl = "http://toolbarqueries.google.com/tbr? Client = navclient-auto & features = Rank & q = info: "; $ hash = substr (app_hash_url ($ domain), 9 ); // because the ch value obtained during hash calculation on my website is incorrect, we can see that we need to cut $ resultUrl = $ startUrl from the first 10th bits. $ domain. "& ch = 8 ". $ hash; $ array = get_headers ($ resultUrl, 1); if (! Preg_match ('/403/', $ array [0]) {// This previous article mentioned to determine whether the page can be read accurately, when no pr is available, the api will jump to 403 $ pageContent = file_get_contents ($ resultUrl); $ pageRank = substr ($ pageContent, 9); echo $ pageRank ;} else {echo "0" ;}}?>

Code 2

This is the code that passes the local test, operating system WIN7, PHP version 5.2.14

 > 23) & 0x1FF) | $ hash <9;} return sprintf ("8% x", $ hash ); // It seems that the WIN host can calculate the exact ch value directly} $ domain1 = $ _ COOKIE ['comment _ author_url _'. COOKIEHASH]; $ domain = substr ($ domain1, 7); $ startUrl = "http://toolbarqueries.google.com/tbr? Client = navclient-auto & features = Rank & q = info: "; $ resultUrl = $ startUrl. $ domain. '& ch = '. app_hash_url ($ domain); $ array = get_headers ($ resultUrl, 1); if (! Preg_match ('/403/', $ array [0]) {$ pageContent = file_get_contents ("$ resultUrl"); $ pageRank = substr ($ pageContent, 9 ); echo $ pageRank;} else {echo '0' ;}}?>

If you want to use it elsewhere to query the PR of some websites, modify it.$domainThe value is enough. I'm tired of writing. You can't give me more than 30 comments as you did in the last two articles.
