随着移动设备的普及，网站也会迎来越来越多移动设备的访问。用适应PC的页面，很多时候对手机用户不友好，那么有些时候，我们需要判断用户是否用手机访问，如果是手机的话，就跳转到指定的手机友好页面。这里就介绍一下，如何判断用户是否用手机访问。

[php] view plaincopy

<?php
/*
*@Descrition:判断用户是否手机访问
*
*
*/
$agent = check_wap();
if($agent){
header('Location:http://www.goole.com');//重定向
exit;
}
//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-|googlebot-Mobile|YahooSeeker\/M1A1-R2D2|android|iphone|ipad|mobi|palm|palmos|pocket|portalmmm|ppc;|smartphone|sorce|xda |xda_)/i', $_SERVER['HTTP_USER_AGENT'])){
return true;
}else{
return false;
}
}
//这个函数是从php框架剥离的判断是否为手机移动终端的函数
function is_mobile_request(){
$_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';
$mobile_browser = '0';
if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT']))){
$mobile_browser++;
}
if(isset($_SERVER['HTTP_X_WAP_FROFILE'])){
$mobile_browser++;
}
if(isset($_SERVER['HTTP_PROFILE'])){
$mobile_browser++;
}
$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'], 0, 4));
$mobile_agents = $mobile_agents = array(
'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',
'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',

);
if(in_array($mobile_ua, $mobile_agents)){
$mobile_browser++;
}
if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false){
$mobile_browser++;
}
//Pre-final check to reset everything if the user is on windows
if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false){
$mobile_browser++;
}
if($mobile_browser > 0){
return true;
}else{
return false;
}
}
?>
