APNS PHP Not Sending Notifications - php

Question

I've set up and APNS Provider Server using PHP. I connect to Apple's APNS Server with no errors, and the script seems to run fine, cycling through all the devices and sending the payload. However, notifications aren't being received on the devices that have subscribed to notifications. Can someone please help me find the error in my code?
$message = $_POST['message'];
echo "Posted Message: $message<br />";
$message = str_replace("'", "\'", $message);
echo "Formatted message: $message<br />";
$title = $_POST['title'];
$title = str_replace("'", "\'", $title);
echo "Formatted Title: $title<br />";
$category = $_POST['category'];
echo "Category: $category<br />";
$alert = array('title' => "$title", 'body' => "$message");
foreach ($alert as $key => $value){
echo "Key: $key Value: $value<br />";
}
ini_set("display_errors",1);
$apnsHost = 'gateway.push.apple.com';
$apnsPort = 2195;
$apnsCert = 'apns.pem';
$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);
$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 2, STREAM_CLIENT_CONNECT, $streamContext);
if ($error!="" || $errorString!=""){
echo "Error Connecting: $error : $errorString<br />";
}
else{
echo "No Error Connecting<br />";
}
$query = "INSERT INTO notifications (`title`, `message`, `category`) VALUES (\"$title\", \"$message\", \"$category\")";
echo "Insert Query: $query<br />";
$result1 = mysqli_query($connection, $query);
$query = "SELECT * FROM notifications ORDER BY notification_id DESC";
$result931 = mysqli_query($connection, $query);
$row = $result931->fetch_assoc();
$notification_id = $row[notification_id];
$query = "SELECT * FROM category_subscriptions WHERE category_id='$category' ORDER BY device_id";
$result1 = mysqli_query($connection, $query);
echo "Subscriber Query: $query<br />";
while($row = $result1->fetch_assoc()) {
$device_id = $row[device_id];
$query = "SELECT * FROM devices WHERE device_id='$device_id' ORDER BY device_id";
$result = mysqli_query($connection,$query);
while($r = $result->fetch_assoc()) {
$deviceToken = $r[device_token];
$badge = $r[badge_value] + 1;
if ($r[accepts_alerts]==1) {
if ($r[accepts_badges]==1) {
if ($r[accepts_sounds]==1) {
$payload['aps'] = array('alert' => $alert, 'badge' => $badge, 'sound' => 'default');
} else {
$payload['aps'] = array('alert' => $alert, 'badge' => $badge);
}
}
else if ($r[accepts_sounds]==1) {
$payload['aps'] = array('alert' => $alert, 'sound' => 'default');
}
else {
$payload['aps'] = array('alert' => $alert);
}
$payload1 = json_encode($payload);
echo "Payload: $payload1<br />";
echo "<br /> Sending to Device Token: $deviceToken<br />";
$apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $deviceToken)) . chr(0) . chr(strlen($payload1)) . $payload1;
echo "APNS Message: $apnsMessage<br />";
fwrite($apns, $apnsMessage);
$query6 = "UPDATE devices SET badge_value = $badge WHERE device_id='$device_id'";
$result6 = mysqli_query($connection,$query6);
$query7 = "INSERT INTO notification_map (`device_id`, `notification_id`, `viewed`) VALUES ($device_id, $notification_id, \"false\")";
$result7 = mysqli_query($connection,$query7);
}
}
}
fclose($apns);

Answer 1

Perform following steps:
1. Check if pem file is valid or not.
2. check if port 2195 is open on your server or not.
3. if your pem file is of development mode the use "ssl://gateway.sandbox.push.apple.com:2195" to connect to apns otherwise if your pem file is of production mode the use "ssl://gateway.push.apple.com:2195" .
check if passpharas is correct.
check this sample code:
<?php
// Put your device token here (without spaces):
$deviceToken = 'fefb03ba6adcea310cf3f455dae16fec4f63b4ba4d96103c20d594a04efd7c2a';
// Put your private key's passphrase here:
$passphrase = 'Welcome#1';
// Put your alert message here:
$message = 'My first push notification!';
////////////////////////////////////////////////////////////////////////////////
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
// Open a connection to the APNS server
$fp = stream_socket_client(
'ssl://gateway.sandbox.push.apple.com:2195', $err,
$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp)
exit("Failed to connect: $err $errstr" . PHP_EOL);
echo 'Connected to APNS' . PHP_EOL;
// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'default',
'title' => 'testing title'
);
// 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, $msg, strlen($msg));
if (!$result)
echo 'Message not delivered' . PHP_EOL;
else
echo 'Message successfully delivered' . PHP_EOL;
// Close the connection to the server
fclose($fp);

Upon further reading of the documentation, I believe I have figured out my problem. I had one database table that held the device tokens for both development and production versions of the app. Apparently when trying to send a production notification it was closing the connection after sending a development device token. I'm not sure why the fwrite command wasn't sending errors after the connection closed, but since I deleted the development device tokens from the database table, it appears to be working now.
