php实现扫描二维码根据浏览器类型访问不同下载地址，php浏览器类型

<&#63;php
$Agent = $_SERVER['HTTP_USER_AGENT'];
preg_match('/android|iphone/i',$Agent,$matches);
if (strtolower($matches[0]) == 'android') {
// echo "安卓";
header("Location: ".$GLOBALS["public_appconfig"]["app"]['android']."'");
} elseif (strtolower($matches[0]) == 'iphone') {
header("'Location: ".$GLOBALS["public_appconfig"]["app"]['ios']."'");
}else{
//不确定是什么系统或者是pc
header("Location: ".$GLOBALS["public_appconfig"]["app"]['android']."'");
}
&#63;>
Copy after login

常常看到网上二维码登录，问PHP程序中怎实现二维码登录？

首页你要知道二维码可以翻译成一些文字或者字符。
过程：
对一个用户生成一个随机验证字符串，然后生成二维码，当用户扫描二维码时对应到这个用户，然后登录该用户。

当然，在这个过程中要注意保密和安全措施。
 

怎实现扫描二维码，实现网址自动跳转？

能否自动访问就看你手机安装的二维码扫描软件的功能了
大部分二维码扫描软件读取到网址会自动跳转，有些会先询问你是否打开
