因为工作需我们写一个电脑手机共用一个域名，当是手机用户是就访问手机页面，如果是电脑用户就访问web页面，下面我们找到判断为手机用户php代码分享给大家。

网上找到的

手机访问，原理是手机通过移动公司的代理服务器进行的访问。那么我们就可以理解是一台普通电脑使用了代理服务器。当手机通过代理服务器访问的时候，http头信息会毫无疑问的包含一个信息：via。这个信息提供了有价值的判断信息。
例如河南移动取得的via信息是：

http/1.1 hazz-b-gw001-wap(infox-wisg, huawei technologies)
河南联通的via信息是：

zxwap gateway,zte technologies

代码

代码如下	复制代码
// check if wap by xhatfunction check_wap() { return stristr($_SERVER['HTTP_VIA'],"wap") ? true : false; }

这样做的结果是没有人能伪造手机访问，判断绝对准确。自然，这样对于网上流行的手机wap模拟器也做了屏蔽—-从根本上屏蔽。
这样肯定不行。

在网上又看到这一样一个

php判断手机浏览器的函数，代码如下，加入了对ipad和android的判断

立即学习“PHP免费学习笔记（深入）”；

代码如下

复制代码

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

}

测试后还是有问题，不讲你也知道，后来看到了wordpress的 function.php 文件这样一段

代码如下

复制代码

//判断是否属手机
function is_mobile() {
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$mobile_agents = Array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi","android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio","au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu","cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ","fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi","htc","huawei","hutchison","inno","ipad","ipaq","ipod","jbrowser","kddi","kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo","mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-","moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia","nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-","playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo","samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank","sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit","tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin","vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce","wireless","xda","xde","zte");
$is_mobile = false;
foreach ($mobile_agents as $device) {
  if (stristr($user_agent, $device)) {
   $is_mobile = true;
   break;
  }
}
return $is_mobile;
}
