本文实例讲述了php实现微信模拟登陆、获取用户列表及群发消息功能。分享给大家供大家参考，具体如下：

<?php
header('Content-Type: text/html; charset=UTF-8');
/*
调用方式简单说明：
 $arr = array(
  'account' => '公众平台帐号',
  'password' => '密码'
);
$w = new Weixin($arr);
print_r($w->getAllUserInfo());//获取所有用户信息
$w->getUserInfo($groupid, $fakeid);//获取所有用户信息，如果默认分组，则$groupid传0
$w->sendMessage('群发内容'); //群发给所有用户
$w->sendMessage('群发内容',$userId); //群发给特定用户,这里的$userId就是用户的fakeid，数组方式传递
*/
class Weixin {
  public $userFakeid;//所有粉丝的fakeid
  private $_account;//用户名
  private $_password;//密码
  private $url;//请求的网址
