The simple version of php implements WeChat official account to actively push messages

Simulate logging into the WeChat public platform to realize active message sending;

Breaking through the restriction that subscription accounts can only send one message a day.

Use encoding UTF-8
Code address: https://github.com/itziy/wechat
Usage method:

$arr = array( 'account' => 'Public platform account', 'password' => ' Password' );

$w = new Weixin($arr);

//$w->getAllUserInfo();//Get all user information
$w->getUserInfo($groupid, $fakeid);// Get the information of a single user. If it is the default group, then $groupid is 0

$w->sendMessage('Group content'); //Group message to all users

$w->sendMessage('Group content',$ userId); //Group sent to a specific user, the userId here is fakeid

This example is for reference only, and I am not responsible for the legal risks caused by it. Thanks.
