获取微信昵称、头像等信息方法

在PHP文件里加入以下代码：

require_once("getUserInfo/getUserInfo.php");  //获取微信信息php
$test = new Webweixin();        
$userinfo = $test->get_userinfo();
print_r("headimgurl:".$userinfo['headimgurl']."openid:".$userinfo['openid']."nickname:".$userinfo['nickname']."city:".$userinfo['city']."province:".$userinfo['province']."country:".$userinfo['country']."sex:".$userinfo['sex']);

?>

getgetUserInfo.php文件：

require_once("weixin.config.php");
class Webweixin
{
//APPID 默认是服务号
var $APPID = APPID1;
var $APPSECRET = APPSECRET1;

//用户方信息（存储当前交互用户的操作状态，以及状态时效）

var $CODE = '';

weixin.config.php文件：

#define APPID1 "wxd1a93f73a10670a1"
#define APPSECRET1 "2d47501a563bade9d74601d36255d1e7"

通过以上即可实现获取微信用户信息。
