issue in Apple Passwallete integration with php - php

Question

I have generated PASS with my code and also get device id, pushtoken in response from device.
here is code by which I am store all device and Pass information in database.
$params = array(
"get"=>$_GET,
"request"=>$_REQUEST,
"post"=>$_POST,
"server"=>$_SERVER
);
$url = $_SERVER['SCRIPT_URI'];
$myfile = file_put_contents('callback.txt', json_encode($params).PHP_EOL , FILE_APPEND | LOCK_EX);
$content = trim(file_get_contents("php://input"));
$myfile = file_put_contents('log.txt', $content.PHP_EOL , FILE_APPEND | LOCK_EX);
$header = json_encode(getallheaders());
$myfile = file_put_contents('header.txt', $header.PHP_EOL , FILE_APPEND | LOCK_EX);
/*
* store registered device data
* */
$str = $_SERVER['SCRIPT_URI'];
$str = stripslashes($str);
$url_slot = parse_url($str);
$urlArray = explode('/',$url_slot['path']);
$passid = $urlArray['11']; // serial no
$deviceId = $urlArray['8'];
$passtype = $urlArray['10'];
try {
$dbh = new PDO('mysql:host=localhost;dbname=''', 'yyyy', 'zzzz');
$stmt = $dbh->prepare("INSERT INTO devices_passes (device_id, pass_id, pass_type, created, modified) VALUES
(:device_id,:pass_id,:pass_type,:created,:modified)");
$stmt->bindParam(':device_id', $device_id);
$stmt->bindParam(':pass_id', $pass_id);
$stmt->bindParam(':pass_type', $pass_type);
$stmt->bindParam(':created', date('d-m-y'));
$stmt->bindParam(':modified', date('d-m-y'));
$device_id = $deviceId;
$pass_id = $passid;
$pass_type = $passtype;
$stmt->execute();
$dbh = null;
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
try {
$dbh = new PDO('mysql:host=localhost;dbname=yyyy', 'uuuuu', 'yyyyyy');
$stmt = $dbh->prepare("INSERT INTO devices (push_token) VALUES
(:push_token)");
$stmt->bindParam(':push_token', $push_token);
$push_token = $content['pushToken'];
$stmt->execute();
$dbh = null;
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
But when I send push notification to device , it will not reflect anything in device.
here is code of sending push notification to device.
<?php
$apnsHost = 'gateway.push.apple.com';
$apnsPort = 2195;
$apnsCert = 'apple_push_notification_production.pem';
$push_token = 'my token';
$passIdentify = 'pass.yyyyy.xxxx';
$payload = '{}';
$msg = chr(0) . pack('n', 32) . pack('H*', $push_token) . pack('n', strlen($payload)) . $payload . pack('n', strlen($passIdentify)) . $passIdentify;
$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);
$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 2, STREAM_CLIENT_CONNECT, $streamContext);
fwrite($apns, $msg);
#socket_close($apns);
fclose($apns);
?>
Can you please help me when I am going wrong ??
