網(wǎng)上倒是能搜到一大把，不過(guò)都是千篇一律的復(fù)制來(lái)復(fù)制去的，也不夠全面，我這里整理了一份比較全面的代碼：
復(fù)制代碼 代碼如下:
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 '';
}
php技術(shù)：php 判斷訪客是否為搜索引擎蜘蛛的函數(shù)代碼，轉(zhuǎn)載需保留來(lái)源！
