With the popularization of mobile devices, more and more mobile devices will access websites. Pages adapted to PCs are often unfriendly to mobile phone users. in some cases, we need to determine whether users are accessed by mobile phones. if they are mobile phones, they will jump to the specified mobile phone friendly page. Here we will introduce how to determine whether a user can access the website through a mobile phone.

The custom functions are as follows:

$ Agent = check_wap (); if ($ agent) {header ('Location: http://www.nowamagic.net '); exit;} // check if wap function check_wap () {// check whether it is a wap proxy first, and the accuracy is high if (stristr ($ _ SERVER ['http _ VIA '], "wap") {return true ;} // check whether the browser accepts WML. elseif (strpos (strtoupper ($ _ SERVER ['http _ ACCEPT ']), "VND. WAP. WML ")> 0) {return true ;} // Check USER_AGENT elseif (preg_match ('/(blackberry | configuration \/cldc | hp-| 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 _)/I ', $ _ SERVER ['http _ USER_AGENT']) {return true;} else {return false ;}}

Another function is used to determine whether a mobile terminal is a mobile phone from the PHP framework:

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));     $mobile_agents = array(   'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',   'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',   'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',   'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',   'newt','noki','oper','palm','pana','pant','phil','play','port','prox',   'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar',   'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-',   'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp',   'wapr','webc','winw','winw','xda','xda-'  );     if(in_array($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;   }
