现在手机移动设备越来越普及，也越来越智能，使用手机浏览网页已经比较流行了，所以，作为wordpress主题开发者，你必须好好考虑如何应对手机移动用户了。
这是一段php通用的判断移动浏览器的函数，原理比较简单，就是判断浏览器返回的user_agent，条件包括手机系统、品牌和窗口大小。
以wordpress为例，在主题的functions.php内加上如下代码，目前已包含常见移动浏览器的useragent，基本上可以涵盖可能会用手机上网的用户群了。
functionis_mobile(){ $user_agent=$_SERVER['HTTP_USER_AGENT']; $mobile_browser=Array( "mqqbrowser",//手机QQ浏览器 "operamobi",//手机opera "juc","iuc",//uc浏览器 "fennec","ios","applewebKit/420","applewebkit/525","applewebkit/532","ipad","iphone","ipaq","ipod", "iemobile","windowsce",//windowsphone "240x320","480x640","acer","android","anywhereyougo.com","asus","audio","blackberry","blazer","coolpad","dopod","etouch","hitachi","htc","huawei","jbrowser","lenovo","lg","lg-","lge-","lge","mobi","moto","nokia","phone","samsung","sony","symbian","tablet","tianyu","wap","xda","xde","zte" ); $is_mobile=false; foreach($mobile_browseras$device){ if(stristr($user_agent,$device)){ $is_mobile=true; break; } } return$is_mobile;}
