php判断用户是否手机访问代码，php判断访问代码

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( $agent )
{
 header('Location: http://www.bkjia.com');
 exit;
}
// check if wap
function check_wap(){
 // 先检查是否为wap代理，准确度高
 if(stristr($_SERVER['HTTP_VIA'],"wap")){
   return true;
 }
 // 检查浏览器是否接受 WML.
 elseif(strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0){
   return true;
 }
 //检查USER_AGENT
 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'])){
   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() 
{ 
$_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) &#63; $_SERVER['ALL_HTTP'] : ''; 
$mobile_browser = '0'; 
if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) 
 $mobile_browser++; 
if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false)) 
 $mobile_browser++; 
if(isset($_SERVER['HTTP_X_WAP_PROFILE'])) 
 $mobile_browser++; 
if(isset($_SERVER['HTTP_PROFILE'])) 
 $mobile_browser++; 
$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4)); 
$mobile_agents = array( 
   'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac', 
   'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno', 
   'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-', 
   'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-', 
   'newt','noki','oper','palm','pana','pant','phil','play','port','prox', 
   'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar', 
   'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-', 
   'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp', 
   'wapr','webc','winw','winw','xda','xda-' 
   ); 
if(in_array($mobile_ua, $mobile_agents)) 
 $mobile_browser++; 
if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false) 
 $mobile_browser++; 
// Pre-final check to reset everything if the user is on Windows 
if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false) 
 $mobile_browser=0; 
// But WP7 is also Windows, with a slightly different characteristic 
if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false) 
 $mobile_browser++; 
if($mobile_browser>0) 
 return true; 
else
 return false; 
}

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($_SERVER['HTTP_X_WAP_PROFILE'])) {
    return true;
  }
  //如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
  if (isset($_SERVER['HTTP_VIA'])) {
    //找不到为flase,否则为true
    if(stristr($_SERVER['HTTP_VIA'], "wap"))
    {
      return true;
    }
  }
  //脑残法，判断手机发送的客户端标志,兼容性有待提高
  if (isset($_SERVER['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',
      'phone',
    );
    // 从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($_SERVER['HTTP_ACCEPT'])) {
    // 如果只支持wml并且不支持html那一定是移动设备
    // 如果支持wml和html但是wml在html之前则是移动设备
    if ((strpos($_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;
}
