$ref = $_SERVER['HTTP_REFERER']; $SE = array('/search?', 'images.google.', 'web.info.com', 'search.', 'del.icio.us/search', 'soso.com', '/search/', '.yahoo.'); foreach ($SE as $source) { if (strpos($ref,$source)!==false) { setcookie("sevisitor", 1, time()+3600, "/", ".yourdomain.com"); $sevisitor=true; } } function wordpress_from_searchengine(){ global $sevisitor; if ($sevisitor==true || $_COOKIE["sevisitor"]==1) { return true; } return false; } 使用说明：
