PHP 实现判断用户是否手机访问_PHP

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：

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

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：

代码很简单，功能很实用，非常适合将其放入项目中，希望小伙伴们能够喜欢。
