To send push notifications in iOS using PHP, you need to follow these steps:

Step 1: Create an Apple Developer Account To send push notifications in iOS, you need an Apple Developer Account. If you don’t have an Apple Developer Account, you can create one by visiting the Apple Developer website.

Step 2: Create an iOS certificate After creating an Apple Developer Account, you need to create an iOS certificate. To create an iOS certificate, follow these steps:

  1. Go to the Apple Developer website.
  2. Select “Certificates, Identifiers & Profiles”.
  3. Select “Certificates”.
  4. Click on the “+” button.
  5. Select “Apple Push Notification service SSL (Sandbox & Production)”.
  6. Follow the on-screen instructions to create a certificate.

Step 3: Generate the .pem file After creating an iOS certificate, you need to generate the .pem file. The .pem file contains the private key and the certificate that are required to send push notifications. To generate the .pem file, follow these steps:

  1. Open the Keychain Access app on your Mac.
  2. Select “My Certificates”.
  3. Find the iOS certificate that you created in Step 2.
  4. Expand the certificate and the private key.
  5. Select both the certificate and the private key.
  6. Right-click and select “Export 2 items”.
  7. Choose the .p12 file format and save the file to your computer.
  8. Open Terminal and navigate to the directory where you saved the .p12 file.
  9. Run the following command: openssl pkcs12 -in myCertificate.p12 -out myKey.pem -nodes -clcerts

Step 4: Send push notifications using PHP After generating the .pem file, you can send push notifications using PHP. Here is an example code for sending push notifications in iOS using PHP:

<?php

// Put your device token here (without spaces):
$deviceToken = 'YOUR_DEVICE_TOKEN';

// Put your private key's passphrase here:
$passphrase = 'YOUR_PRIVATE_KEY_PASSPHRASE';

// Put your alert message here:
$message = 'Hello World!';

////////////////////////////////////////////////////////////////////////////////

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'PATH_TO_YOUR_PEM_FILE');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

// Open a connection to the APNS server
$fp = stream_socket_client(
    'ssl://gateway.push.apple.com:2195', $err,
    $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

if (!$fp)
    exit("Failed to connect: $err $errstr" . PHP_EOL);

// Create the payload body
$body['aps'] = array(
    'alert' => $message,
    'sound' => 'default'
    );

// Encode the payload as JSON
$payload = json_encode($body);

// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server
$result = fwrite($fp,
