PHP to determine whether the user's phone access code _php tips

With the popularity of mobile devices, the site will also usher in more and more mobile devices access. Used to adapt to the PC page, often unfriendly to mobile phone users, then sometimes, we need to determine whether the user to access the phone, if it is a mobile phone, jump to the designated mobile friendly page. Here is a brief introduction, how to determine whether users use mobile phone access.

The custom functions are as follows:

$agent = Check_wap ();
if ($agent)
{
 header (' location:http://www.jb51.net ');
 Exit;
}
Check if WAP
function Check_wap () {
 ///Checking for WAP proxy first, high accuracy
 if (stristr ($_server[' Http_via '), "WAP") { return
   true;
 }
 Check to see if the browser accepts WML.
 ElseIf (Strpos strtoupper ($_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; 
 }

A function that is stripped from the PHP frame to determine whether the mobile terminal is a mobile phone:

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

To share a personal use of

function Isphone () {//If http_x_wap_profile must be mobile device if (Isset ($_server[' http_x_wap_profile ')) {return true; //If the VIA information contains WAP it must be a mobile device and some service providers block the information if (Isset ($_server[' Http_via ')) {//Cannot find flase, otherwise true if Stristr ($_serv
