判断当前浏览器是否为微信内置浏览器 MicroMessenger
通过微信内置浏览器的 User Agent
首先我们通过 PHP 内置的 $_SERVER["HTTP_USER_AGENT"] server 数组来获取 User Agent。
iPhone 通过微信内置浏览器访问网页时得到 User Agent 是：
Mozilla/5.0 (iPhone; CPU iPhone OS 6_1_3 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Mobile/10B329 MicroMessenger/5.0.1Android 通过微信内置浏览器访问网页时得到 User Agent 是：
Mozilla/5.0 (Linux; U; Android 2.3.6; zh-cn; GT-S5660 Build/GINGERBREAD) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1 MicroMessenger/4.5.255JS 判断
function is_weixin(){
var ua = navigator.userAgent.toLowerCase();
if(ua.match(/MicroMessenger/i)=="micromessenger") {
return true;
} else {
return false;
}
}PHP 判断
function is_weixin(){
if ( strpos($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger') !== false ) {
return true;
}
return false;
