PHP code _php instance to get Google PR value

Today, after the update blog program, suddenly found that Google Toolbar PR bar added a little, but has been the Google Toolbar PR because of the buffer problem, so that the current display of the PR value is not necessarily the current page PR value, so to check the next, found blog site (HTTP/ mlsx.xplore.cn/) PR value rose to 3, but the home page (http://mlsx.xplore.cn) is still 2. Rattling, celebrate.

But Glemir this morning told me his blog early has reached 3, so I am a little jealous, and associated with the Rachel Blog, they update are not I diligent, but their PR basically do not need me poor. So I came to two self-comforting conclusions:

1) Rachel PR is the same as mine, because his travels log is popular, I do not have his handwriting.

2) Glemir PR rose faster than mine, that is because he used a good blog program--wordpress

Haha, laugh at yourself.

Turn to the point, affixed to get Google PR value code, the statement is not I write, just modify, checksum algorithm temporarily still do not know.
