This is an old script that I used to use for sending notifications. I don’t remember the source, on the other hand, it has been modified a couple of times already.

Even though I could manage to send notifications with this script, the Apple server was rejecting the connection after the amount reaches more than 50. It was usually getting cut off around 70. So it needs to get some management for not sending in a loop, like threading or whatever.

header('content-type: text/html; charset: utf-8');

$passphrase = 'my_secret_pass';
 
// you can post a variable to this string or edit the message here
if (!isset($_POST['msg'])) {
$_POST['msg'] = "Notification message here!";
}
 
// tr_to_utf function needed to fix the Turkish characters
$message = tr_to_utf($_POST['msg']);
