ahhh its doctorow spamming SEO forums

[doctorow]

alex dude, why would you suspect me?

Thank you for the code, it's working. Thanks man. You are all really great.

Wow!!!

I did'nt knew that I had such a big secret in my wallet Thanks to Gemini who told me abt the same.

Cheers

the c code works for me, but the php code is returning different results. for 'http://www.example.com/' i get 62147418112 on my powerbook (big endian) and 62920760850 on x86 linux (little endian).

[alexstapleton]

only works on little endian machines obviously. there is a big endian version of the hash function i believe. i will look into big endian compatibility.

doh! i forgot to prepend 'info:' so my results were also wrong for little endian. sorry, my bad.

[alexstapleton]

actually your result was right for little endian.
you can use http://alex.vort-x.net/google/ the form there to verify ch values if you want.

[alexstapleton]

erm what am i talking about. yes it was wrong. lol :S
http://www.example.com = 6540747202

I just developed a complete all-in-one function in PHP that using The Google Checksum Calculator, by Alex Stapleton, Andy Doctorow, Vijay "Cyberax" Bhatter, and a few others, (https://www.mobileread.com/forums/sho...9&postcount=87) and XMLize.php by Hans Anderson (http://www.hansanderson.com/php/xml/) automatically calculates the PageRank for a page. Try it at:

And the source code is at:

Hope you like it

Is that url supposed to be working? It doesnt for me anyway. Or do I have to put http:// infront of the url? Or maybe "link:"???

(tested it all, even urlencoded, still doesnt give correct ch)

[UnknownZ]

You need to put http://
for example if your website is www.unregistered.com , just put in http://www.unregistered.com ...it will give you correct checksum.

And thanks also to zenitram for the code.

Good Work from Zenitram :cool. But you guys really do not know how much loss you have made for the guys who are charging money for this piece of code

They have earned a lot already.

Ok, I found the bugg why your page is giving wrong ch for me...

When I look at your url after it has been submitted, the value for "url" is like this:

http%3A%2F%2Fwww.example.com

BUT for me the toolbar priduces this:

http%3A%2F%2Fwww.example.com%2

For every request it puts %2 after the call... why? Is this an client thing? I got WinXP and running IE6.0, all patched and done.
