Websocket服务器出现RSA_padding_check_PKCS1_type_2错误

I want to send a message from my SSL Website to my php-websocket server. The server uses a wildcard certificate.

This is the client:

var wsUri = "wss://ticket.qwellcode.de:9001";
websocket_qcode_intern = new WebSocket(wsUri);

And this my Websocket server:

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);    
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);
socket_bind($socket, 0, $port);    
socket_listen($socket);
...

To decrypt a message (e.g the header) I use the following code:

function decryptString($cryptText)
{
    $keyFile=fopen("PATH/TO/pemfile.pem","r") or die("NOT FOUND");
    $privateKey=fread($keyFile,8192);
    fclose($keyFile);

    openssl_get_privatekey($privateKey);
    $binText = base64_decode($cryptText);

    /* NOT WORK WITH THIS PADDING */
    //openssl_private_decrypt($binText,$clearText,$privateKey,OPENSSL_PKCS1_PADDING);
    openssl_private_decrypt($binText,$clearText,$privateKey);
    print openssl_error_string();
    return($clearText);
}

The problem is that with the padding "OPENSSL_PKCS1_PADDING" (or other paddings) I get the following message:

error:0407106B:rsa routines:RSA_padding_check_PKCS1_type_2:block
type is not 02

With the option "OPENSSL_NO_PADDING" I get crap decoded code like this:

▬♥☺ ø☺  ù♥☻→ª   ↕ FRomTý¤▬3ŵ▬g»►F↕Ñ;nÏágdCH╝  *└

 ♣ ♦☺  D   ↑ ▬  ‼domain.de ☺ ☺
 ♠ ↨ ↑ ↓ ♂ ☻☺  #  3t   ♣ ♣☺

I Use a SSL-Zetificat with the encryption, PKCS #1 SHA-1 - AES 128 CBC with SHA 1.

How can I decrypt this code ? ... I tryed everything .. And yes I know, I can use stream socket.. but I will solve this for me with the "normal" php-socket ...

Why am I having trouble decrypting? Is there a solution?
