PHP website to determine whether a user is a mobile phone access method

In some cases, we need to determine whether the user is using a mobile phone to access, if it is a mobile phone, jump to the designated mobile phone-friendly page. Here's how to tell if a user is using a mobile phone to access it.

The custom functions are as follows:

$agent=Check_wap ();if($agent ){  Header(' Location:http://www.jb51.net '); Exit;} //Check if WAPfunctionCheck_wap () {//first check whether it is a WAP proxy, high accuracy  if(Stristr($_server[' Http_via '], "WAP")){    return true; }  //Check if the browser accepts WML.  ElseIf(Strpos(Strtoupper($_server[' http_accept ']), "VND. Wap. WML ") > 0){    return true; }  //Check User_agent  ElseIf(Preg_match('/(blackberry|configuration\/cldc|hp |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; }}

Another way to decide whether to peel from the PHP framework is the function of the Mobile Terminal: (tested, very comprehensive, recommended)

functionis_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)); $mobile _agents=Array(     ' acs-', ' Alav ', ' Alca ', ' amoi ', ' Audi ', ' Avan ', ' BenQ ', ' bird ', ' Blac ', ' Blaz ', ' brew ', ' cell ', ' cldc ', ' cmd-', ' Dang ' , ' doco ', ' Eric ', ' Hipt ', ' Inno ', ' iPAQ ', ' Java ', ' Jigs ', ' kddi ', ' Keji ', ' Leno ', ' lg-c ', ' lg-d ', ' lg-g ', ' lge-', ' Maui ', ' Maxo ', ' MIDP ', ' mits ', ' mmef ', ' mobi ', ' mot-', ' moto ', ' mwbp ', ' nec-', ' Newt ', ' Noki ', ' oper ', ' palm ', ' pana ', ' Pant ', ' Phil ' , ' play ', ' Port ', ' ProX ', ' qwap ', ' sage ', ' Sams ', ' Sany ', ' sch-', ' sec-', ' send ', ' Seri ', ' sgh-', ' shar ', ' sie-', ' Siem ', ' Smal ', ' Smar ', ' Sony ', ' sph-', ' symb ', ' t-mo ', ' Teli ', ' tim-', ' tosh ', ' tsm-', ' upg1 ', ' upsi ', ' vk-v ', ' Voda ', ' wap-', ' Wapa ' , ' Wapi ', ' wapp ', ' wapr ', ' webc ', ' winw ', ' winw ', ' xda ', ' xda-'    ); if(In_array($mobile _ua,$mobile _agents))   $mobile _browser++; if(Strpos(Strtolower($_server[' All_http ']), ' Operamini ')!==false)   $mobile _browser++; //pre-final Check to reset everything if the user are on Windows if(Strpos(Strtolower($_server[' Http_user_agent ']), ' windows ')!==false)   $mobile _browser=0; //but WP7 was also Windows, with a slightly different characteristic if(Strpos(Strtolower($_server[' Http_user_agent ']), ' windows Phone ')!==false)   $mobile _browser++; if($mobile _browser>0)   return true; Else  return false;
