How to send push notification from PHP to iOS?

Question

PHP

There is a site on Symfony 4.4 & MySQL and it is maximally adapted for mobile devices.
You need to create an iOS application through a WebView with support for push notifications.

The site already has a notification system, but is there a way to integrate a PHP site with an iOS application?
Or do you need another database?

Answer 1

In my opinion, the only correct solution would be to write a web api that accepts post or get requests, returning a json response, and the application in the background will listen to the page with the api and, if the response json changes, parse it and generate a push.
cons:
you need to know the php database
pluses:
we do not burn access to the database, because The application does not store any username or password.
