没有绝对的方法能分别。
提供以下函数,如果不是刻意混淆,成功在99%以上~

function isMobile() {<br />
  if(isset($_SERVER['HTTP_X_WAP_PROFILE'])){<br />
    return TRUE;<br />
  }<br />
<br />
  if(isset($_SERVER['HTTP_VIA']) && stristr($_SERVER['HTTP_VIA'], "wap")){<br />
    return TRUE;<br />
  }<br />
<br />
  if(isset($_SERVER['HTTP_USER_AGENT'])){<br />
    $clientkeywords = array('nokia', 'sony', 'ericsson', 'mot', 'samsung', 'htc', 'sgh', 'lg', 'sharp', 'sie-',<br />
      'philips', 'panasonic', 'alcatel', 'lenovo', 'iphone', 'ipod', 'blackberry', 'meizu', 'android', 'netfront', 'symbian',<br />
      'ucweb', 'windowsce', 'palm', 'operamini', 'operamobi', 'openwave', 'nexusone', 'cldc', 'midp', 'wap', 'mobile');<br />
    if(preg_match("/(" . implode('<br><font color='#FF8000'>------解决方案--------------------</font><br>', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))){<br />
      return TRUE;<br />
    }<br />
  }<br />
<br />
  if(isset($_SERVER['HTTP_ACCEPT'])){<br />
    if((strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') !== false)<br />
          && (strpos($_SERVER['HTTP_ACCEPT'], 'text/html') === false<br />
              <br><font color='#FF8000'>------解决方案--------------------</font><br> (strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') < strpos($_SERVER['HTTP_ACCEPT'], 'text/html')))){<br />
      return TRUE;<br />
