PHP中文网Original: 2017-03-23 13:48:441411browse

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 we will introduce how to determine whether the user is accessing via mobile phone.

The customized functions are as follows:

$agent = check_wap();
if( $agent )
{
  header(&#39;Location: http://www.jb51.net&#39;);
  exit;
}
  
// check if wap 
function check_wap(){
  // 先检查是否为wap代理，准确度高
  if(stristr($_SERVER[&#39;HTTP_VIA&#39;],"wap")){
    return true;
  }
  // 检查浏览器是否接受 WML.
  elseif(strpos(strtoupper($_SERVER[&#39;HTTP_ACCEPT&#39;]),"VND.WAP.WML") > 0){
    return true;
  }
  //检查USER_AGENT
  elseif(preg_match(&#39;/(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&#39;, $_SERVER[&#39;HTTP_USER_AGENT&#39;])){
    return true;       
  }
  else{
    return false;  
  }
}

Another function separated from the PHP framework to determine whether it is a mobile phone terminal: (After testing, it is very comprehensive and recommended to use)

function is_mobile_request()  
{  
 $_SERVER[&#39;ALL_HTTP&#39;] = isset($_SERVER[&#39;ALL_HTTP&#39;]) ? $_SERVER[&#39;ALL_HTTP&#39;] : &#39;&#39;;  
 $mobile_browser = &#39;0&#39;;  
 if(preg_match(&#39;/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i&#39;, strtolower($_SERVER[&#39;HTTP_USER_AGENT&#39;])))  
  $mobile_browser++;  
 if((isset($_SERVER[&#39;HTTP_ACCEPT&#39;])) and (strpos(strtolower($_SERVER[&#39;HTTP_ACCEPT&#39;]),&#39;application/vnd.wap.xhtml+xml&#39;) !== false))  
  $mobile_browser++;  
 if(isset($_SERVER[&#39;HTTP_X_WAP_PROFILE&#39;]))  
  $mobile_browser++;  
 if(isset($_SERVER[&#39;HTTP_PROFILE&#39;]))  
  $mobile_browser++;  
 $mobile_ua = strtolower(substr($_SERVER[&#39;HTTP_USER_AGENT&#39;],0,4));  
 $mobile_agents = array(  
    &#39;w3c &#39;,&#39;acs-&#39;,&#39;alav&#39;,&#39;alca&#39;,&#39;amoi&#39;,&#39;audi&#39;,&#39;avan&#39;,&#39;benq&#39;,&#39;bird&#39;,&#39;blac&#39;,

    );  
 if(in_array($mobile_ua, $mobile_agents))  
  $mobile_browser++;  
 if(strpos(strtolower($_SERVER[&#39;ALL_HTTP&#39;]), &#39;operamini&#39;) !== false)  
  $mobile_browser++;  
 // Pre-final check to reset everything if the user is on Windows  
 if(strpos(strtolower($_SERVER[&#39;HTTP_USER_AGENT&#39;]), &#39;windows&#39;) !== false)  
  $mobile_browser=0;  
 // But WP7 is also Windows, with a slightly different characteristic  
 if(strpos(strtolower($_SERVER[&#39;HTTP_USER_AGENT&#39;]), &#39;windows phone&#39;) !== false)  
  $mobile_browser++;  
 if($mobile_browser>0)  
  return true;  
 else
  return false;
