$passphrase = '';
$deviceToken="8ebf42fd63c37071b9309f938a527189525b777f35571fc249ec1ed2581d3441";
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', "pushCert.pem");
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
// Open a connection to the APNS server
$fp = stream_socket_client(
'ssl://gateway.push.apple.com:2195', $err,

$payload = json_encode($body);
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

Why push notification work sometime and sometime are not? I am getting below warnings when sending a push notification to IOS device

Or

When you are trying to write to the socket. If something goes wrong, fwrite will return false or 0 (depending on the php version) as the return value. When it happens, you must manage it.

By another way, add sleep(5) before fwrite().

You can do something like this :-

try {                           
    $result = fwrite($fp, $msg, strlen($msg));
}
catch (Exception $ex) {
    sleep(5); //sleep for 5 seconds
    $result = fwrite($fp, $msg, strlen($msg));
    if ($result)
    {
        return true;
    }
    else {
        return false;
    }
}

Hope it helps!

can you describe your issue after trying above code ? Is it going in catch block ?? – Shashank Shah Apr 07 '17 at 11:38
It is not going to catch block – Narendra Apr 07 '17 at 11:42
Where is the below setting? so that i can change SSL_write can be changed by setting SSL_MODE_ENABLE_PARTIAL_WRITE and/or SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER. – Narendra Apr 07 '17 at 11:46

I m getting the same issue on production and resolve the issue using below steps

Step 1: Change below 
From 
$fp = stream_socket_client('ssl://gateway.push.apple.com:2195', 
$err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

To below:   
$fp = stream_socket_client('ssl://gateway.push.apple.com:2195', 
$err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);

Step 2: add below line just before the "$result = fwrite($fp, $msg, trlen($msg));"

stream_set_blocking($fp, 0);

Push notification is not working sometime and sometime it works. getting warning SSL3_WRITE_PENDING:bad write retry and SSL: Broken pipe
