如何判断微信内置浏览器(JS & PHP)

最好的判断方式就是通过 User Agent 来判断。

在iPhone下,返回

Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/9B176 MicroMessenger/4.3.2

在Android下,返回

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/4.5.255

不难发现微信浏览器为 MicroMessenger ,并且有版本号,也可以判断手机类型为iPhone还是Android

根据以上内容我们就可以来写php代码了

function is_weixin()

{

if ( strpos($_SERVER[‘HTTP_USER_AGENT’], ‘MicroMessenger’) !== false ) {

return true;

}

return false;

}
通过 JavaScript 判断 代码demo

function is_weixin(){
	var ua = navigator.userAgent.toLowerCase();
	if(ua.match(/MicroMessenger/i)=="micromessenger") {
		return true;
 	} else {
		return false;
	}
}
