use php to get google page rank
Since the google not give a API or interface to get the google page rank, we have to use google toolbar to get the PR. In order to use php to query toolbarqueries.google.com to the get PR, I did a search ,but most of the codes are too old and can’t use or not work well, at last i got following script works well.

there is all the codes :
<?php function StrToNum($Str, $Check, $Magic) { $Int32Unit = 4294967296; // 2^32 $length = strlen($Str); for ($i = 0; $i < $length; $i++) { $Check *= $Magic; //If the float is beyond the boundaries of integer (usually +/- 2.15e+9 = 2^31), // the result of converting to integer is undefined // refer to http://www.php.net/manual/en/language.types.integer.php if ($Check >= $Int32Unit) { $Check = ($Check - $Int32Unit * (int) ($Check / $Int32Unit)); //if the check less than -2^31 $Check = ($Check < -2147483648) ? ($Check + $Int32Unit) : $Check; } $Check += ord($Str{$i}); } return $Check; } //--> for google pagerank /* * Genearate a hash for a url */ function HashURL($String) { $Check1 = StrToNum($String, 0x1505, 0x21); $Check2 = StrToNum($String, 0, 0x1003F); $Check1 >>= 2; $Check1 = (($Check1 >> 4) & 0x3FFFFC0 ) | ($Check1 & 0x3F); $Check1 = (($Check1 >> 4) & 0x3FFC00 ) | ($Check1 & 0x3FF); $Check1 = (($Check1 >> 4) & 0x3C000 ) | ($Check1 & 0x3FFF); $T1 = (((($Check1 & 0x3C0) << 4) | ($Check1 & 0x3C)) <<2 ) | ($Check2 & 0xF0F ); $T2 = (((($Check1 & 0xFFFFC000) << 4) | ($Check1 & 0x3C00)) << 0xA) | ($Check2 & 0xF0F0000 ); return ($T1 | $T2); } //--> for google pagerank /* * genearate a checksum for the hash string */ function CheckHash($Hashnum) { $CheckByte = 0; $Flag = 0; $HashStr = sprintf('%u', $Hashnum) ; $length = strlen($HashStr); for ($i = $length - 1; $i >= 0; $i --) { $Re = $HashStr{$i}; if (1 === ($Flag % 2)) { $Re += $Re; $Re = (int)($Re / 10) + ($Re % 10); } $CheckByte += $Re; $Flag ++; } $CheckByte %= 10; if (0 !== $CheckByte) { $CheckByte = 10 - $CheckByte; if (1 === ($Flag % 2) ) { if (1 === ($CheckByte % 2)) { $CheckByte += 9; } $CheckByte >>= 1; } } return '7'.$CheckByte.$HashStr; } //get google pagerank function getpagerank($url) { $query="http://toolbarqueries.google.com/search?client=navclient-auto&ch=".CheckHash(HashURL($url)).

After a recent google toolbar update, it is needed to use a different url to get this code to work:
use http://toolbarqueries.google.com/tbr?...
instead of http://toolbarqueries.google.com/search?...
I have learn some just right stuff here. Certainly price bookmarking for revisiting. I surprise how so much effort you put to make such a wonderful informative web site.
