网站如何根据浏览器跳转实现自适应移动设备

现在越来越多的移动设备出现，为了让网站更好的适应移动设备，需要针对移动设备匹配专用域名，例如m.u22e.com这样的域名，下面代码在wordpress源码实现如下

自适应移动设备代码

/*根据浏览器跳转*/

define (‘MOBILE_DOMAIN’, ‘m.u22e.com’);

define (‘REAL_DOMAIN’, ‘www.u22e.com’);

if ($_SERVER[‘SERVER_NAME’] == MOBILE_DOMAIN) {

define(‘WP_HOME’ ,’http://’ . MOBILE_DOMAIN);

define(‘WP_SITEURL’,WP_HOME);

define(‘TEMPLATEPATH’, ABSPATH .’wp-content/themes/Ripple_mobile/’);

define(‘STYLESHEETPATH’, ABSPATH .’wp-content/themes/Ripple_mobile/’);

define (‘MOBILE_THEME’, true);

}elseif(strpos($_SERVER[‘HTTP_USER_AGENT’],’baidu Transcoder’)){ //百度转码跳转

header(‘Location: ‘. ‘http://’ . MOBILE_DOMAIN . $_SERVER[“REQUEST_URI”]);

die();

}else{

if (!empty($_GET[‘m_action’])) {

if ($_GET[‘m_action’] == ‘nomobile’) {

setcookie(‘wordpress_mobile_domain_disable’, 1, time()+86400, ‘/’, REAL_DOMAIN, false);

if (!empty($_SERVER[‘HTTP_REFERER’])) {

$go = str_replace(MOBILE_DOMAIN, REAL_DOMAIN, $_SERVER[‘HTTP_REFERER’]);

header (‘location:’.$go);

die();

} else {

header (‘location:’.REAL_DOMAIN);

die();

}

}

}

if (!isset($_COOKIE[‘wordpress_mobile_domain_disable’])) {

header (‘location:http://’ . MOBILE_DOMAIN . $_SERVER[‘REQUEST_URI’]);

}

}

}
