关于PHP在linux下面获取GOOGLE的PR值哪位大侠知道，用PHP查询指定网址的pagerank对环境有什么要求啊，我在windows系统下面任何一台机器能行，在linux下面有的服务器能行，有的不能行！下面是我获取GOOGLE PR值的源码(非原创，只有一点修改) define('GOOGLE_MAGIC', 0xE6359A60); class pageRank{ var $pr; function zeroFill($a, $b){ $z = hexdec(80000000); if ($z & $a){ $a = ($a>>1); $a &= (~$z); $a |= 0x40000000; $a = ($a>>($b-1)); }else{ $a = ($a>>$b); } return $a; } function mix($a,$b,$c){ $a -= $b; $a -= $c; $a ^= ($this->zeroFill($c,13)); $b -= $c; $b -= $a; $b ^= ($a<<8); $c -= $a; $c -= $b; $c ^= ($this->zeroFill($b,13)); $a -= $b; $a -= $c; $a ^= ($this->zeroFill($c,12)); $b -= $c; $b -= $a; $b ^= ($a<<16); $c -= $a; $c -= $b; $c ^= ($this->zeroFill($b,5)); $a -= $b; $a -= $c; $a ^= ($this->zeroFill($c,3)); $b -= $c; $b -= $a; $b ^= ($a<<10); $c -= $a; $c -= $b; $c ^= ($this->zeroFill($b,15)); return array($a,$b,$c); } function GoogleCH($url, $length=null, $init=GOOGLE_MAGIC){ if(is_null($length)) { $length = sizeof($url); } $a = $b = 0x9E3779B9; $c = $init; $k = 0; $len = $length; while($len >= 12) { $a = ($url[$k 0] ($url[$k 1]<<8) ($url[$k 2]<<16) ($url[$k 3]<<24)); $b = ($url[$k 4] ($url[$k 5]<<8) ($url[$k 6]<<16) ($url[$k 7]<<24)); $c = ($url[$k 8] ($url[$k 9]<<8) ($url[$k 10]<<16) ($url[$k 11]<<24)); $mix = $this->mix($a,$b,$c); $a = $mix[0]; $b = $mix[1]; $c = $mix[2]; $k = 12; $len -= 12; } $c = $length; switch($len){ case 11: $c =($url[$k 10]<<24); case 10: $c =($url[$k 9]<<16); case 9 : $c =($url[$k 8]<<8); /* the first byte of c is reserved for the length */ case 8 : $b =($url[$k 7]<<24); case 7 : $b =($url[$k 6]<<16); case 6 : $b =($url[$k 5]<<8); case 5 : $b =($url[$k 4]); case 4 : $a =($url[$k 3]<<24); case 3 : $a =($url[$k 2]<<16); case 2 : $a =($url[$k 1]<<8); case 1 : $a =($url[$k 0]); } $mix = $this->mix($a,$b,$c); /* report the result */ return $mix[2]; } //converts a string into an array of integers containing the numeric value of the char function strord($string){ for($i=0;$i<strlen($string);$i ) { $result[$i] = ord($string{$i}); } return $result; } function printrank($url){ $ch = "6".$this->GoogleCH($this->strord("info:" . $url)); $fp = fsockopen("www.google.com", 80, $errno, $errstr, 30); if(!$fp){ echo "$errstr ($errno)<br />/n"; }else{ $out = "GET /search?client=navclient-auto&ch=" . $ch .
