网上倒是能搜到一大把，不过都是千篇一律的复制来复制去的，也不够全面，我这里整理了一份比较全面的代码：
function is_spider(){
$robot = 0;
$USER_AGENT = strtolower($_SERVER['HTTP_USER_AGENT']);
if(strpos($USER_AGENT,"bot")) $robot = 1;
if(strpos($USER_AGENT,"spider")) $robot = 1;
if(strpos($USER_AGENT,"slurp")) $robot = 1;
if(strpos($USER_AGENT,"mediapartners-google")) $robot = 1;
if(strpos($USER_AGENT,"fast-webcrawler")) $robot = 1;
if(strpos($USER_AGENT,"altavista")) $robot = 1;
if(strpos($USER_AGENT,"ia_archiver")) $robot = 1;
if($robot == 1){
//do something
}
return '';
}
