通过上面的三条 User Agent 信息，可以创造它们都有一个共同的 YisouSpider 字段，也便是说 User Agent 中含有 YisouSpider 字段的来访者即为神马搜索引擎的蜘蛛。
php代码
<?php//飞鸟慕鱼博客function is_yisouspider(){ $ua= addslashes(strtolower($_SERVER['HTTP_USER_AGENT'])); if (strpos($ua, 'yisouspider') !== false) {return true; } return false;}?>
函数调用：
<?phpif(is_yisouspider()){ echo 'yes';}else{ echo 'no';}?>
