thinkphp _php instance of the method of judging a visitor as a mobile or PC end

The examples in this paper describe how thinkphp judge a visitor as a mobile or PC end. Share to everyone for your reference. The implementation method is as follows:

First, the question:

Recently prepared to make a small upgrade to their website, so that the user in the mobile phone QR code scan display suitable for mobile phone end to show the template "I use is ThinkPHP3.0", the code is reference to others

Second, the realization method:

Here's a simple two-step approach:

The system version number and the browser and its version number (only the Mobile information is in the array in the pasted code, so it is only possible to determine if one of the values is an array).

According to the values in the array to determine whether the visitor is mobile phone, pad, such as mobile, if yes, specify the project path, the name of your mobile phone end template such as Copy code code as follows: Define (' app_name ', ' mobi ');

Define (' App_path ', './mobi/');

The following code, I try to add comments:
Copy CodeThe code is as follows://Determine whether it belongs to mobile
The code looks a lot, in fact, the array inside appears much and disorderly, do not be intimidated by the surface phenomenon Oh!
function Is_mobile () {
$user _agent = $_server[' http_user_agent ');

$mobile _agents = Array ("240x320", "Acer", "Acoon", "acs-", "Abacho", "Ahong", "Airness", "Alcatel", "Amoi", "Android", " Anywhereyougo.com "," applewebkit/525 "," applewebkit/532 "," Asus "," Audio "," Au-mic "," Avantogo "," Becker "," BenQ "," Bilbo "," Bird "," BlackBerry "," blazer "," Bleu "," cdm-"," Compal "," Coolpad "," Danger "," Dbtel "," Dopod "," Elaine "," Eric ", "Etouch", "Fly", "Fly_", "fly-", "Go.web", "goodaccess", "Gradiente", "Grundig", "Haier", "Hedy", "Hitachi", "HTC", " Huawei "," Hutchison "," Inno "," ipad "," iPAQ "," ipod "," Jbrowser "," KDDI "," kgt "," KWC "," Lenovo "," LG "," Lg2 "," Lg3 "," LG4 ", "Lg5", "Lg7", "Lg8", "Lg9", "lg-", "lge-", "Lge9", "Longcos", "Maemo", "Mercator", "Meridian", "Micromax", "MIDP", "Mini", " Mitsu "," MMM "," MMP "," Mobi "," mot-"," Moto "," nec-"," NetFront "," Newgen "," Nexian "," Nf-browser "," Nintendo "," Nitro "," Nokia "," Nook "," Novarra "," Obigo "," Palm "," Panasonic "," Pantech "," Philips "," Phone "," pg-"," PlayStation "," Pocket "," Pt-"," qc-"," Qtek "," Rover "," Sagem "," sama "," Samu "," Sanyo "," Samsung "," sch-"," Scooter "," sec-"," Sendo "," sgh-"," Sharp "," Siemens "," Sie-"," "SoftBank", "Sony", "Spice", "Sprint", "SPV", "Symbian", "tablet", "Talkabout", "tcl-", "Teleca", "Telit", "Tianyu", " Tim-"," Toshiba "," TSM "," Up.browser "," Utec "," Utstar "," Verykool "," Virgin "," vk-"," Voda "," Voxtel "," VX "," WAP "," Wellco "," Wig Browser "," Wii "," Windows CE "," wireless "," XDA "," Xde "," ZTE ");
$is _mobile = false;
foreach ($mobile _agents as $device) {//The value is iterated over here to find out if any of the above strings have occurred
if (Stristr ($user _agent, $device)) {//stristr Find out if the guest information is in the above array, the PC side does not exist.
$is _mobile = true;
Break
}
}
return $is _mobile;
}
Define (' Think_path ', './core/');
if (Is_mobile ()) {//Jump to WAP Group
Echo ' You are mobile phone-side access, has jumped to the mobile side ';
Define (' App_name ', ' mobi ');
Define (' App_path ', './mobi/');
}else{
Echo ' You are a PC-side access ';
Define (' App_name ', ' Home ');
Define (' App_path ', './home/');
}
Define (' App_debug ', false);
Require Think_path. ' core.php ';

It is hoped that this article will be helpful to everyone's thinkphp framework design.
