PHP socket_read. problem with received data?

Question

PHP

I write Echo server
a piece of code:

while($client && $msg = socket_read($client, self::MSG_BYTE_LIMIT) ) {
        if ( $msg == 'quit' ) {
          die("Disconnected.\n");
        }

        socket_write($client, $msg);
      }

I connect via telnet, enter quit, and what? and nothing! even if you
crack stupidly, the received $msg does not compare

Answer 1

most likely you have "quit\n" there

Answer 2

Caret symbol?
The solution to your problem with Telnet is already in the dock.
