This is a custom Message implementing the Safari Push Notification message payload.

@duccio If needed we can add an example file as sample_push.php, sample_push_custom.php, etc.
Hope it helps.

Hello @delitestudio, sorry for the delay. If you an add an example file (e.g. sample_push_safari.php) I will merge ASAP. Thanks 😉

Hi @duccio, I have committed a sample_push_safari.php file that uses the same text used in the official Apple documentation to ease users integrating Safari notifications in their PHP projects.

Thank you so much @delitestudio!
