写项目时整理的小笔记(4)

1. 判断是否为手机端(tp3)

    function ismobile() {
      // 如果有HTTP_X_WAP_PROFILE则一定是移动设备
         if (isset ($_SERVER['HTTP_X_WAP_PROFILE']))
            return true;
      //此条摘自TPM智能切换模板引擎,适合TPM开发
          if(isset ($_SERVER['HTTP_CLIENT']) &&'PhoneClient'==$_SERVER['HTTP_CLIENT'])
            return true;
      //如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
        if (isset ($_SERVER['HTTP_VIA']))
    //找不到为flase,否则为true
          return stristr($_SERVER['HTTP_VIA'], 'wap') ? true : false;
    //判断手机发送的客户端标志,兼容性有待提高
      if (isset ($_SERVER['HTTP_USER_AGENT'])) {
          $clientkeywords = array(
              'nokia','sony','ericsson','mot','samsung','htc','sgh','lg','sharp','sie-','philips','panasonic','alcatel','lenovo','iphone','ipod','blackberry','meizu','android','netfront','symbian','ucweb','windowsce','palm','operamini','operamobi','openwave','nexusone','cldc','midp','wap','mobile'
        );
  //HTTP_USER_AGENT中查找手机浏览器的关键字
        if (preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))) {
            return true;
        }
    }
//协议法,因为有可能不准确,放到最后判断
    if (isset ($_SERVER['HTTP_ACCEPT'])) {
// 如果只支持wml并且不支持html那一定是移动设备
// 如果支持wmlhtml但是wmlhtml之前则是移动设备
        if ((strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') !== false) && (strpos($_SERVER['HTTP_ACCEPT'], 'text/html') === false || (strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') < strpos($_SERVER['HTTP_ACCEPT'], 'text/html')))) {
            return true;
        }
    }
    return false;
}
