Push notification work on browser doesn't on commandline - php

Question

I have php file for running apns. And it does work when i call web page on browser. However it doesn't work on terminal with calling
php deneme.php
I comfirm that .pem file is correctly created. And also determine its location in php file is correct too(because work correctly on browser). I run out with option. I hope you give me an idea.
The deneme.php file is:
<?php
$apnsServer = 'ssl://gateway.sandbox.push.apple.com:2195';
$privateKeyPassword = 'MyPassword123';
$message = 'Test Push Notifications';
$deviceToken =
'2877b691ffd9a3edfa45ee31ff25083f1845e016e7902d130eb09713b1c2ed2f';
$pushCertAndKeyPemFile = $_SERVER['DOCUMENT_ROOT'].'/ck.pem';// 'ck.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);
?>

There are no $_SERVER[] superglobals available when running from CLI, since there is no server running. Replace$_SERVER['DOCUMENT_ROOT'].'/ck.pem'; with the absolute path to your ck.pem file.
