使用PHP實現蜘蛛訪問日志統計

本篇文章是對使用PHP實現蜘蛛訪問日志統計的代碼進行了詳細的分析介紹需要的朋友參考下   復制代碼 代碼如下:

　　
$useragent = addslashes(strtolower($_SERVER[HTTP_USER_AGENT]));

 if (strpos($useragent googlebot)!== false){$bot = Google;}
 elseif (strpos($useragentmediapartnersgoogle) !== false){$bot = Google Adsense;}
 elseif (strpos($useragentbaiduspider) !== false){$bot = Baidu;}
 elseif (strpos($useragentsogou spider) !== false){$bot = Sogou;}
 elseif (strpos($useragentsogou web) !== false){$bot = Sogou web;}
 elseif (strpos($useragentsosospider) !== false){$bot = SOSO;}
 elseif (strpos($useragentspider) !== false){$bot = Spider;}
 elseif (strpos($useragentyahoo) !== false){$bot = Yahoo;}
 elseif (strpos($useragentmsn) !== false){$bot = MSN;}
 elseif (strpos($useragentmsnbot) !== false){$bot = msnbot;}
 elseif (strpos($useragentsohu) !== false){$bot = Sohu;}
 elseif (strpos($useragentyodaoBot) !== false){$bot = Yodao;}
 elseif (strpos($useragenttwiceler) !== false){$bot = Twiceler;}
 elseif (strpos($useragentia_archiver) !== false){$bot = Alexa_;}
 elseif (strpos($useragentiaarchiver) !== false){$bot = Alexa;}
 elseif (strpos($useragentslurp) !== false){$bot = 雅虎;}
 elseif (strpos($useragentbot) !== false){$bot = 其它蜘蛛;}
 if(isset($bot)){
     $fp = @fopen(bottxta);
     fwrite($fpdate(Ymd H:i:s)"t"$_SERVER["REMOTE_ADDR"]"t"$bot"t"http://$_SERVER[SERVER_NAME]$_SERVER["REQUEST_URI"]"rn");
     fclose($fp);
 }
