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:
Copy Code code as follows:
$agent = Check_wap ();
if ($agent)
{
Header (' location:http://www.nowamagic.net ');
Exit
}
Check if WAP
function Check_wap () {
Check for WAP agent 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;
}
}
And then a split from the PHP framework to determine whether the mobile phone mobile terminal functions:
Copy Code code as follows:
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));
$mobile _agents = Array (
' The consortium ', ' acs-', ' Alav ', ' Alca ', ' amoi ', ' Audi ', ' Avan ', ' BenQ ', ' bird ', ' Blac ',
' Blaz ', ' brew ', ' cell ', ' cldc ', ' cmd-', ' Dang ', ' doco ', ' Eric ', ' Hipt ', ' Inno ',
' iPAQ ', ' Java ', ' Jigs ', ' kddi ', ' Keji ', ' Leno ', ' lg-c ', ' lg-d ', ' lg-g ', ' lge-',
' Maui ', ' Maxo ', ' MIDP ', ' mits ', ' mmef ', ' mobi ', ' mot-', ' moto ', ' mwbp ', ' nec-',
' Newt ', ' Noki ', ' oper ', ' palm ', ' pana ', ' Pant ', ' Phil ', ' play ', ' Port ', ' ProX ',
' Qwap ', ' sage ', ' Sams ', ' Sany ', ' sch-', ' sec-', ' send ', ' Seri ', ' sgh-', ' Shar ',
' sie-', ' Siem ', ' smal ', ' Smar ', ' Sony ', ' sph-', ' symb ', ' t-mo ', ' Teli ', ' tim-',
' Tosh ', ' tsm-', ' upg1 ', ' upsi ', ' vk-v ', ' Voda ', ' wap-', ' wapa ', ' wapi ', ' Wapp ',
' Wapr ', ' webc ', ' winw ', ' winw ', ' xda ', ' xda-'
);
if (In_array ($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 '), ' 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;
}
The code is very simple, the function is very practical, is very suitable puts it in the project, hoped the small partner can like.
