Read single bytes from socket stream in PHP

$data = socket_read($this->socket, 5);

    $counter = strlen($data); 
    for($i = 0; $i < $counter; ++$i) { 
        $char = (int)$data[$i]; 
        echo "\nByte $i: $char\n"; 
    }

The client sends two bytes to the server, and even when I read 5, it still only receives 2. The issue is that the byte is reading as 0. It's not reading it properly. How can I read the actual byte/byte array.

Thanks in advance!

If the client only sent two bytes, why do you want five? Try using socket_recv() instead to get explicit return value of bytes read.
