之前有一个案例用到判断用户是手机访问还是电脑访问，然后给用户展示相应的页面。最初是用js去做，但是准确度不高，最终采用了PHP来做，经测试基本上都能判断准确。

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。

自定义的函数如下：

$agent = check_wap();
if( $agent )
{
 header(&#39;Location: http://www.php.cn/&#39;);
 exit;
}
// check if wap
function check_wap(){
 // 先检查是否为wap代理，准确度高
 if(stristr($_SERVER[&#39;HTTP_VIA&#39;],"wap")){
   return true;
 }
 // 检查浏览器是否接受 WML.
 elseif(strpos(strtoupper($_SERVER[&#39;HTTP_ACCEPT&#39;]),"VND.WAP.WML") > 0){
   return true;
 }
 //检查USER_AGENT
 elseif(preg_match(&#39;/(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&#39;, $_SERVER[&#39;HTTP_USER_AGENT&#39;])){
   return true;      
 }
 else{
   return false; 
 }
}

再来一个从PHP框架剥离的判断是否为手机移动终端的函数：

function is_mobile_request() 
{ 
$_SERVER[&#39;ALL_HTTP&#39;] = isset($_SERVER[&#39;ALL_HTTP&#39;]) ? $_SERVER[&#39;ALL_HTTP&#39;] : &#39;&#39;; 
$mobile_browser = &#39;0&#39;; 
if(preg_match(&#39;/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i&#39;, strtolower($_SERVER[&#39;HTTP_USER_AGENT&#39;]))) 
 $mobile_browser++; 
if((isset($_SERVER[&#39;HTTP_ACCEPT&#39;])) and (strpos(strtolower($_SERVER[&#39;HTTP_ACCEPT&#39;]),&#39;application/vnd.wap.xhtml+xml&#39;) !== false)) 
 $mobile_browser++; 
if(isset($_SERVER[&#39;HTTP_X_WAP_PROFILE&#39;])) 
 $mobile_browser++; 
if(isset($_SERVER[&#39;HTTP_PROFILE&#39;])) 
 $mobile_browser++; 
$mobile_ua = strtolower(substr($_SERVER[&#39;HTTP_USER_AGENT&#39;],0,4)); 
$mobile_agents = array(

if(in_array($mobile_ua, $mobile_agents))

 $mobile_browser++; 
if($mobile_browser>0) 
 return true;

再给大家分享一个个人使用的

function isPhone() {
  // 如果有HTTP_X_WAP_PROFILE则一定是移动设备
  if (isset($_SERVER[&#39;HTTP_X_WAP_PROFILE&#39;])) {
    return true;
  }
  //如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
  if (isset($_SERVER[&#39;HTTP_VIA&#39;])) {
    //找不到为flase,否则为true
    if(stristr($_SERVER[&#39;HTTP_VIA&#39;], "wap"))
    {
      return true;
    }
  }
  //脑残法，判断手机发送的客户端标志,兼容性有待提高
  if (isset($_SERVER[&#39;HTTP_USER_AGENT&#39;])) {
    $clientkeywords = array (

      return true;
    }
  }
  //协议法，因为有可能不准确，放到最后判断
  if (isset($_SERVER[&#39;HTTP_ACCEPT&#39;])) {
    // 如果只支持wml并且不支持html那一定是移动设备
    // 如果支持wml和html但是wml在html之前则是移动设备
    if ((strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;vnd.wap.wml&#39;) !== false) && (strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;text/html&#39;) === false || (strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;vnd.wap.wml&#39;) < strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;text/html&#39;)))) {
