Using PHP to send iOS Push Notifications via APNs

Question

I have implemented Push-Notifications into my Project and everything works fine so far. I've tried sending Notifications through Pusher and this worked out just fine. But I have to send them through PHP, which isn't working yet. I found many old explanations on how to make this happen, but none of them seem to work for me.

This is what I'm trying to work with:

    // APNs Push testen auf Token
$deviceToken = $_GET['key']; // Device-Token

// Payload erstellen und JSON codieren
$payload['aps'] = array('alert' => 'TitleText', 'badge' => 1, 'sound' => 'default');
$payload = json_encode($payload);

$apnsHost = 'gateway.sandbox.push.apple.com';
$apnsPort = 2195;
$apnsCert = 'certificate.pem';

// Stream erstellen
$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'certificate.cer', $apnsCert);

$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 2, STREAM_CLIENT_CONNECT, $streamContext);
if ($apns)
{
  // Nachricht erstellen und senden
  $apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $deviceToken)) . chr(0) . chr(strlen($payload)) . $payload;
  fwrite($apns, $apnsMessage);

  // Verbindung schliessen
  fclose($apns);
}
else
{
  echo "Fehler!";
  var_dump($error);
  var_dump($errorString);
}

Try using this php script , make sure that the .pem certificate exits in same path as that php script when you run it , also get a correct device token

 <?php
        /* We are using the sandbox version of the APNS for development. For production
        environments, change this to ssl://gateway.push.apple.com:2195 */
        $apnsServer = 'ssl://gateway.sandbox.push.apple.com:2195';
        /* Make sure this is set to the password that you set for your private key
        when you exported it to the .pem file using openssl on your OS X */
        $privateKeyPassword = '1234';
        /* Put your own message here if you want to */
        $message = 'Welcome to iOS 7 Push Notifications';
        /* Pur your device token here */
        $deviceToken =
        '05924634A8EB6B84437A1E8CE02E6BE6683DEC83FB38680A7DFD6A04C6CC586E';
        /* Replace this with the name of the file that you have placed by your PHP
        script file, containing your private key and certificate that you generated
        earlier */
        $pushCertAndKeyPemFile = 'PushCertificateAndKey.pem';
        $stream = stream_context_create();
        stream_context_set_option($stream,
        'ssl',
        'passphrase',
        $privateKeyPassword);
        stream_context_set_option($stream,
        'ssl',
        'local_cert',
        $pushCertAndKeyPemFile);

        $connectionTimeout = 20;
        $connectionType = STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT;
        $connection = stream_socket_client($apnsServer,
        $errorNumber,
        $errorString,
        $connectionTimeout,
        $connectionType,
        $stream);
        if (!$connection){
        echo "Failed to connect to the APNS server. Error no = $errorNumber<br/>";
        exit;
        } else {
        echo "Successfully connected to the APNS. Processing...</br>";
        }
        $messageBody['aps'] = array('alert' => $message,
        'sound' => 'default',
        'badge' => 2,
        );
        $payload = json_encode($messageBody);
        $notification = chr(0) .
        pack('n', 32) .
        pack('H*', $deviceToken) .
        pack('n', strlen($payload)) .
        $payload;
        $wroteSuccessfully = fwrite($connection, $notification, strlen($notification));
        if (!$wroteSuccessfully){
        echo "Could not send the message<br/>";
        }
        else {
        echo "Successfully sent the message<br/>";
        }
        fclose($connection);

  ?>

Here is new updates on script, As Apple changed notification url:

<?php
    if ( defined("CURL_VERSION_HTTP2") && (curl_version()["features"] & CURL_VERSION_HTTP2) !== 0) {
        $ch = curl_init();
        $body ['aps'] = array (
            "alert" => array (
                "title"  => "hii",
            ),
            "sound"  => "default"
        );
        $curlconfig = array(
            CURLOPT_URL => "https://api.development.push.apple.com/3/device/device_token",
            CURLOPT_RETURNTRANSFER =>true,
            CURLOPT_POSTFIELDS => json_encode($body),
            CURLOPT_SSLCERT =>"apns.pem",
            CURLOPT_SSLCERTPASSWD => "123456",
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_2_0,
            CURLOPT_VERBOSE => true
        );
        curl_setopt_array($ch, $curlconfig);
        $res = curl_exec($ch);
        if ($res === FALSE) {
                echo('Curl failed: ' . curl_error($ch));
        }
        curl_close($ch);
    }else{
        echo "No HTTP/2 support on client.";
    }
       
    ?>

<?php

        $serverKey = 'AAAA8XYL2Y8:APA91bF1fsddfgffdssdsdfsdsdsda8zyWJTgs0OSeiRlk9WQqLwKn51VkMH_XSbpRuiCTU-Fdi2hoV8JY8ST7gCBQe4dlMFASDbr5Oci1bLmg9tyl5dlxyFDauWWCMItUNdFGWO_CWhpHwSIbvbqYwlCnoRd7ucB';
        $notification = array(

        $arrayToSend = array(

        curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        //Send the request
        echo $response = curl_exec($ch);
        //Close request
        if ($response === FALSE) {
            die('FCM Send Error: ' . curl_error($ch));
        }
        curl_close($ch);
        mysql_query("INSERT INTO `tbl_notifications`(`n_activity_name`,`n_user_id`,`n_device_id`, `n_notification`) VALUES ('$activitytype','$StudentAdmissionId','$id','$response')");
        // #Echo Result Of FireBase Server
        return $response;
    }

• Use this for php & mysql backend for pusihing notification on android and ios on the same time

• Here token of apns server is stored in db and pass to send fcm
