Villain博客文章摘要
这篇文章介绍了使用PHP编写的一段代码，用于记录不同搜索引擎蜘蛛代理的访问统计信息。代码通过分析用户代理头（User-Agent）来识别常用的搜索引擎（如Google、百度、360等），并将访问日志写入指定的文本文件中。记录内容包括访问时间、访问地址、代理IP及访问来源，帮助分析不同搜索引擎的流量来源及访问行为。
<?php//蜘蛛访问统计
$useragent = addslashes(strtolower($_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($useragent,'yisouspider') !== false){$bot = 'SMSpider';} elseif (strpos($useragent,'bingbot') !== false){$bot = 'bingbot';}
