以下是我用在自己网站上的在线统计对搜索引擎的判断，无法判断的搜索引擎会将主机头信息写入日志，然后根据主机头信息分析新的搜索引擎厂商的特征然后扩充。
$searchengine='';
$agent = $_SERVER["HTTP_USER_AGENT"];
if (eregi('sogou',$agent))
{
$searchengine="sogou spider";
}
elseif (eregi('Baiduspider',$agent))
{
$searchengine="Baiduspider";
}
elseif (eregi('SpiderMan',$agent))
{
$searchengine="SpiderMan";
}
elseif (eregi('psbot',$agent))
{
$searchengine="psbot";
}
elseif (eregi('Googlebot',$agent))
{
$searchengine="Googlebot";
}
elseif (eregi('msnbot',$agent))
{
$searchengine="msnbot";
}
elseif (eregi('lanshanbot',$agent))
{
$searchengine="lanshanbot";
}
elseif (eregi('Slurp',$agent))
{
$searchengine="Slurp";
}
elseif (eregi('Snapbot',$agent))
{
$searchengine="Snapbot";

$searchengine=$enginename;
