PHP判断是否手机访问

PHP判断是否手机访问

这里有俩个办法，可以看看

<?php 
$agent = check_wap();
if($agent)
{
header('Location: https://www.hackhp.com/m/');//转到手机对应页面
exit;
}
?>

<?php 
// check if wap 
function check_wap(){
// 先检查是否为wap代理，准确度高
if(stristr($_SERVER['HTTP_VIA'],"wap")){
return true;
}
// 检查浏览器是否接受 WML.
elseif(strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0){
return true;
   }
   //检查USER_AGENT
   elseif(preg_match('/(blackberry|configuration\/cldc|hp |hp-|htc |htc_|htc-|iemobile|kindle|midp|mmp|motorola|mobile|nokia|opera mini|opera |Googlebot-Mobile|YahooSeeker\/M1A1-R2D2|android|iphone|ipod|mobi|palm|palmos|pocket|portalmmm|ppc;|smartphone|sonyericsson|sqh|spv|symbian|treo|up.browser|up.link|vodafone|windows ce|xda |xda_)/i', $_SERVER['HTTP_USER_AGENT'])){
return true; 
}
else{
return false;
   }
}
?>
