define('ISROBOT', getrobot());if(defined('NOROBOT') && ISROBOT) {	exit(header("HTTP/1.1 403 Forbidden"));}

上面这段代码,据说是防止机器人访问的,我不理解哪里代表是机人呢

判断机器人的函数是这么写的,这里面有啥玄机吗
function getrobot() {	if(!defined('IS_ROBOT')) {		$kw_spiders = 'Bot|Crawl|Spider|slurp|sohu-search|lycos|robozilla';		$kw_browsers = 'MSIE|Netscape|Opera|Konqueror|Mozilla';		if(preg_match("/($kw_browsers)/", $_SERVER['HTTP_USER_AGENT'])) {			define('IS_ROBOT', FALSE);		} elseif(preg_match("/($kw_spiders)/", $_SERVER['HTTP_USER_AGENT'])) {			define('IS_ROBOT', TRUE);		} else {			define('IS_ROBOT', FALSE);		}	}	return IS_ROBOT;}

Bot-微软的bing
Spider-百度
slurp-雅虎
其他几个不知道,不过这也只能防止正常的抓取,人家伪造了也不一定能防止

难道就没有一个好办办吗

流氓要抓也没办法,不过一般的搜索引擎都遵循robots协议

$kw_spiders = 'Bot|Crawl|Spider|slurp|sohu-search|lycos|robozilla';是啥意思呢

Bot|Crawl|Spider|slurp|sohu-search|lycos|robozilla
是正则要匹配的模式
Bot,Spider...都是蜘蛛的标识,一般的搜索引擎都会写
