PHP: Google PageRank Checker

[gon]

see this

it shows an error:

Your client does not have permission to get URL /search?client=navclient-auto&ch=6-2147439921&ie=UTF-8&oe=UTF-8&features=Rank&q=info:http%3A%2F%2Fa.com from this server. (Client IP address: xxx.xxx.xxx.xxx)

do you see the same error ?

I need a php script that show the PR of a web...

thank you !

Thank you very much KRL, it's so interesting, but I need to get PageRank in a PHP variable. Do you see the same error with this?

[GrouchyAdmin]

It's been blocked. You can't do that. People abused it, so Google killed it. You'll have to find another means.

[gooddomains]

contact google

Thanks !

Well, to directly access that url, you need to forge your user-agent reply. Also, google regularly blocks websites that automatically perform the lookups. I think those big sites that are still running actually cycle connections to google through a set of proxies. Then when one proxy gets blocked, it just removes the result, and a new set of proxies are just added into their config.

Are you sure you're doing it right? i.e. the ch= is correctly calculated?

Never mind.. you're not.. with the correct ch value the url you posted works.

they changed 'Magic number' algorith few months ago...You should try this:

PHP Code:

OK, Tempest, I believe that you are right, I've been looking for and I have found that many servers don't calculate the right value for $ch, in my local server it works fine, but when I upload to my server it crash. My economy is weak, but I can pay $15 (paypal) for who changes me the code so that works in my server, I paste the code bellow:

PHP Code:

<?php

            $a |= 0x40000000;
            $a = ($a>>($b-1));
        }
        else
        {
            $a = ($a>>$b);
        }
        return $a;
}

I had a Google PR checker on www.cyberwebmasters.com but Google blocked it. Fair enough to as I was checking 5000 domains everyday for 3 weeks. lol

Wish I had some code to give you but mine is in Perl. I doubt anyone will do what you need for $15. You might be better off looking around for other code to find one that works.

The problem is most likely related to a fundamental flaw in PHP in that it doesn't do bitwise (unsigned 32/64 bit ints) properly. There are some work arounds but you have to know where the error is occuring.

[GrouchyAdmin]

The pagerank checker in axslinks works, and it looks like an elder version of the same damn code. Works on 3 different hosts that I've tested it on - if it doesn't work for you, there's probably other problems with your server. If it does work for you, feel free to dump the cash to darksoul, because I stole it from his, and he got it from wherever.
