This article introduces the function of using HTTP_USER_AGENT to determine the type of mobile phone in PHP. Friends in need can refer to it.

Regarding the method of determining the type of mobile phone, the previous article of Programmer Home has mentioned it. Related reference articles: Determine whether mobile phone access PHP code to determine whether mobile access is available

Use HTTP_USER_AGENT to determine the phone type. The code is as follows:

<?php
/**
* 判断手机类型
* by bbs.it-home.org
*/
function is_mobile_request()  
{  
      $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_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-',

            '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',

            );  
      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;  
}

Attached is a simple method written by myself:

<?php
//能过http_user_agent检测是否手机访问
$ua = strtolower($_SERVER['HTTP_USER_AGENT']);

$uachar = "/(nokia|sony|ericsson|mot|samsung|sgh|lg|
philips|panasonic|alcatel|lenovo|cldc|midp|mobile|wap)/i";

if(($ua == '' || preg_match($uachar, $ua))&& !strpos(strtolower($_SERVER['REQUEST_URI']),'wap'))
{
    $Loaction = 'wap/';

    if (!empty($Loaction))
    {
        ecs_header("Location: $Loaction\n");

        exit;
    }
}
?>
