fwrite(): SSL operation failed with code 1. OpenSSL Error messages:\nerror:1409F07F:SSL routines:SSL3_WRITE_PENDING:bad write retry IN PHP

Question

I have got same questions in stackoverflow and tried all answers but no help. I am not getting what is the error.

Here is my function that i am using:

Answer 1

Thanks for replying I found similar solutions in google that you should write to socket again. In m case code was throwing exception so I am managing that. So Now I am doing it like this

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

// Send it to the server
try {                           
    $result = fwrite($fp, $msg, strlen($msg));
}
catch (Exception $ex) {
    // try once again for socket busy error (fwrite(): SSL operation failed with code 1.
    // OpenSSL Error messages:\nerror:1409F07F:SSL routines:SSL3_WRITE_PENDING)
    sleep(5); //sleep for 5 seconds
    $result = fwrite($fp, $msg, strlen($msg));
    if ($result)
    {
        return true;
    }
    else {
        return false;
    }
}

Now it is not throwing that error in most of the cases. What I found that it happens when socket is busy so I am trying to write again after 5 seconds now. So I guess this should not come again. It is not live yet but in our testing we did not found this issue again. Can you suggest that I am going in right direction? When this code will be live then there will be a huge number of push notifications then in that case will it work fine or is there any other solution in your mind? Thanks for help :)
