熟悉DZ的朋友都知道，Discuz系统是会根据浏览器客户端的不同，切换PC版或手机版。那么具体是怎么实现的了解吗？
实现手机端判断，依靠了一个函数,名为checkmobile(),位置在/source/function/function_core.php中，如下所示：
返回2是触屏版，返回3是WML版。再配合source/class/discuz/discuz_application.php中的代码，就实现了跳转。
- function checkmobile() {
- global $_G;
- $mobile = array();
- static $touchbrowser_list =array(‘iphone’, ‘android’, ‘phone’, ‘mobile’, ‘wap’, ‘netfront’, ‘java’, ‘opera mobi’, ‘opera mini’,
- ‘ucweb’, ‘windows ce’, ‘symbian’, ‘series’, ‘webos’, ‘sony’, ‘blackberry’, ‘dopod’, ‘nokia’, ‘samsung’,
- ‘palmsource’, ‘xda’, ‘pieplus’, ‘meizu’, ‘midp’, ‘cldc’, ‘motorola’, ‘foma’, ‘docomo’, ‘up.browser’,
- ‘up.link’, ‘blazer’, ‘helio’, ‘hosin’, ‘huawei’, ‘novarra’, ‘coolpad’, ‘webos’, ‘techfaith’, ‘palmsource’,
- ‘alcatel’, ‘amoi’, ‘ktouch’, ‘nexian’, ‘ericsson’, ‘philips’, ‘sagem’, ‘wellcom’, ‘bunjalloo’, ‘maui’, ‘smartphone’,
- ‘iemobile’, ‘spice’, ‘bird’, ‘zte-‘, ‘longcos’, ‘pantech’, ‘gionee’, ‘portalmmm’, ‘jig browser’, ‘hiptop’,
- ‘benq’, ‘haier’, ‘^lct’, ‘320×320’, ‘240×320’, ‘176×220’, ‘windows phone’);
- static $wmlbrowser_list = array(‘cect’, ‘compal’, ‘ctl’, ‘lg’, ‘nec’, ‘tcl’, ‘alcatel’, ‘ericsson’, ‘bird’, ‘daxian’, ‘dbtel’, ‘eastcom’,
- ‘pantech’, ‘dopod’, ‘philips’, ‘haier’, ‘konka’, ‘kejian’, ‘lenovo’, ‘benq’, ‘mot’, ‘soutec’, ‘nokia’, ‘sagem’, ‘sgh’,
- ‘sed’, ‘capitel’, ‘panasonic’, ‘sonyericsson’, ‘sharp’, ‘amoi’, ‘panda’, ‘zte’);
- static $pad_list = array(‘ipad’);
- $useragent = strtolower($_SERVER[‘HTTP_USER_AGENT’]);
- if(dstrpos($useragent, $pad_list)) {
- return false;
- }
- if(($v = dstrpos($useragent, $touchbrowser_list, true))){
- $_G[‘mobile’] = $v;
- return ‘2’;
- }
- if(($v = dstrpos($useragent, $wmlbrowser_list))) {
- $_G[‘mobile’] = $v;
- return ‘3’; //wml版
- }
- $brower = array(‘mozilla’, ‘chrome’, ‘safari’, ‘opera’, ‘m3gate’, ‘winwap’, ‘openwave’, ‘myop’);
- if(dstrpos($useragent, $brower)) return false;
- $_G[‘mobile’] = ‘unknown’;
- if(isset($_G[‘mobiletpl’][$_GET[‘mobile’]])) {
- return true;
- } else {
- return false;
- }
- }
