php determines whether the user accesses the code via mobile phone, php determines the access code

With the popularity of mobile devices, the website will also receive more and more visits from mobile devices. Pages adapted to PCs are often not friendly to mobile phone users. Sometimes, we need to determine whether the user is accessing via a mobile phone. If so, jump to the designated mobile phone-friendly page. Here is an introduction to how to determine whether a user is accessing via a mobile phone.

The customized functions are as follows:

$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; 
 }
}

Here is another function separated from the PHP framework to determine whether it is a mobile terminal:

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',

   ); 
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;

Let me share with you one for personal use

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',

    // 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;
