Quickly send an Apple Push Notification using PHP

apn-server.php

<?php 
$apnsHost = 'gateway.sandbox.push.apple.com';
$apnsCert = 'apns-dev.pem';
$apnsPort = 2195;

$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);

$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 2, STREAM_CLIENT_CONNECT, $streamContext);

$payload['aps'] = array('alert' => 'Oh hai!', 'badge' => 1, 'sound' => 'default');
$output = json_encode($payload);
$token = pack('H*', str_replace(' ', '', $token))
$apnsMessage = chr(0) . chr(0) . chr(32) . $token . chr(0) . chr(strlen($output)) . $output;
fwrite($apns, $apnsMessage);

socket_close($apns);
fclose($apns);

The previous code has serious flaws with the packaging of bytes, Try this instead:
http://www.kubilayerdogan.net/sample-apple-push-notification-php-script/

Or just update the existing sample with this code, which works just fine:

/* original code until line 8 goes here */

// Better payload with title and body; for silent push omit 'alert' and 'sound'
$payload['aps'] = array(
	'alert' => array(
		'title' => 'Sample push number ' . mt_rand(100, 999),
		'body' => 'Sample push body goes here'
	),
	'badge' => 9,
	'sound' => 'default',
	'my_value_1' => 'more data',
	'my_value_2' => 'even more data'
);

// JSON-encode payload
$output = json_encode($payload, JSON_NUMERIC_CHECK);

// Cancel if payload too long
if(strlen($output) > 2048){
	die('Payload too long ('.strlen($output).'): Aborted');
}

// Build the binary notification (correctly)
$token = pack('H*', str_replace(' ', '', $token)); /* str_replace useless since token does not appear to have spaces? */
$apnsMessage = chr(0).pack('n', 32).$token.pack('n', strlen($output)).$output;

// Send it to the server
$result = fwrite($apns, $apnsMessage, strlen($apnsMessage));

// Result returns number of bytes sent on success, false otherwise
if(intval($result) > 0){
	// Push sent
	$response = $result.' bytes sent. $payload size is: '.strlen($output).' (payload limit is 2048 bytes)';
	fclose($apns);
}else{
	// Push failed
	$error = error_get_last();
	$response = (is_array($error) ? $error['message'] : 'undefined error');
}

// Show result
die($response);
