Is it possible to send push for ios from the site?

Question

iOS

The point is the following. You need to send push notifications from the site that will be generated in php, for example:
$notification = date('dmY','1531396041');
if(date('dmY',time()) = $notification){
send push to ios
} The
question is, is it possible to send push without an application on the device?
Or you need an application, register it, etc.

Answer 1

It is forbidden. Safari iOS does not support "push notification" and "serviceworker". Only apps can receive notifications.

Answer 2

Where do you want to send PUSH?
To get PUSH, you need to include an APNS certificate in your "product".
