使用PHP实现蜘蛛访问日志统计

使用PHP实现蜘蛛访问日志统计

　　本篇文章是对使用PHP实现蜘蛛访问日志统计的代码进行了详细的分析介绍，需要的朋友参考下

　　复制代码 代码如下:

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

　　if (strpos($useragent, 'googlebot')!== false){$bot = 'Google';}

　　elseif (strpos($useragent,'mediapartners-google') !== false){$bot = 'Google Adsense';}

　　elseif (strpos($useragent,'baiduspider') !== false){$bot = 'Baidu';}

　　elseif (strpos($useragent,'sogou spider') !== false){$bot = 'Sogou';}

　　elseif (strpos($useragent,'sogou web') !== false){$bot = 'Sogou web';}

　　elseif (strpos($useragent,'sosospider') !== false){$bot = 'SOSO';}

　　elseif (strpos($useragent,'360spider') !== false){$bot = '360Spider';}

　　elseif (strpos($useragent,'yahoo') !== false){$bot = 'Yahoo';}

　　elseif (strpos($useragent,'msn') !== false){$bot = 'MSN';}

　　elseif (strpos($useragent,'msnbot') !== false){$bot = 'msnbot';}

　　elseif (strpos($useragent,'sohu') !== false){$bot = 'Sohu';}

　　elseif (strpos($useragent,'yodaoBot') !== false){$bot = 'Yodao';}

　　elseif (strpos($useragent,'twiceler') !== false){$bot = 'Twiceler';}

　　elseif (strpos($useragent,'ia_archiver') !== false){$bot = 'Alexa_';}

　　elseif (strpos($useragent,'iaarchiver') !== false){$bot = 'Alexa';}

　　elseif (strpos($useragent,'slurp') !== false){$bot = '雅虎';}

　　elseif (strpos($useragent,'bot') !== false){$bot = '其它蜘蛛';}

　　if(isset($bot)){

　　    $fp = @fopen('bot.txt','a');

　　    fwrite($fp,date('Y-m-d H:i:s')."t".$_SERVER["REMOTE_ADDR"]."t".$bot."t".'http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"]."rn");

　　    fclose($fp);

　　}
