php实现微信模拟登陆、获取用户列表及群发消息功能示例

调用方式简单说明：
 $arr = array(

  '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
