How to simulate login on WeChat with PHP and send messages to users

This article mainly introduces the method of PHP to implement WeChat simulated login and send messages to users. It can realize the function of sending text, pictures and graphics. It involves the relevant operating skills of PHP for WeChat interface. Friends in need can refer to the following

The details are as follows:

 '公众平台帐号',
  'password' => '密码'

$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
*/
$w = new Weixin(array('account'=>'771948524@qq.com','password'=>'1259012345'));
$w->sendMessage('hello', 'oXLujjp9y1311QldQKht7iyq83RM');
