PHP屏蔽蜘蛛访问代码及常用搜索引擎的HTTP_USER_AGENT

PHP 屏蔽蜘蛛访问代码 代码

：

常用搜索引擎名与 HTTP_USER_AGENT对应值

百度baiduspider

谷歌googlebot

搜狗sogou

腾讯SOSOsosospider

雅虎slurp

有道youdaobot

Bingbingbot

MSNmsnbot

Alexais_archiver

PHP;"> function is_crawler() { $userAgent = strtolower($_SERVER['HTTP_USER_AGENT']); $spiders = array( 'Googlebot',// Google 爬虫 'Baiduspider',// 百度爬虫 'Yahoo! Slurp',// 雅虎爬虫 'YodaoBot',// 有道爬虫 'msnbot' // Bing爬虫 // 更多爬虫关键字 ); foreach ($spiders as $spider) { $spider = strtolower($spider); if (strpos($userAgent,$spider) !== false) { return true; } } return false; }

下面的PHP 代码附带了更多的蜘蛛标识

PHP;"> function isCrawler() { echo $agent= strtolower($_SERVER['HTTP_USER_AGENT']); if (!empty($agent)) { $spiderSite= array( "TencentTraveler","Baiduspider+","BaiduGame","Googlebot","msnbot","Sosospider+","Sogou web spider","ia_archiver","Yahoo! Slurp","YoudaoBot","Yahoo Slurp","MSNBot","Java (Often spam bot)","BaiDuSpider","Voila","Yandex bot","BSpider","twiceler","Sogou Spider","Speedy Spider","Google AdSense","Heritrix","Python-urllib","Alexa (IA Archiver)","Ask","Exabot","Custo","OutfoxBot/YodaoBot","yacy","SurveyBot","legs","lwp-trivial","Nutch","StackRambler","The web archive (IA Archiver)","Perl tool","MJ12bot","Netcraft","MSIECrawler","WGet tools","larbin","Fish search",); foreach($spiderSite as $val) { $str = strtolower($val); if (strpos($agent,$str) !== false) { return true; } } } else { return false; } } if (isCrawler()){ echo "你好蜘蛛精！"; } else{ echo "你不是蜘蛛精啊！"; }

使用PHP实现蜘蛛访问日志统计

PHP;"> $useragent = addslashes(strtolower($_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($useragent,'iaarchiver') !== false){$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"]."\r\n");
fclose($fp);
}
