socket_accept — Accepts a connection on a socket
$socket
   )
   After the socket socket has been created
   using socket_create(), bound to a name with
   socket_bind(), and told to listen for connections
   with socket_listen(), this function will accept
   incoming connections on that socket. Once a successful connection
   is made, a new socket resource is returned, which may be used
   for communication. If there are multiple connections queued on
   the socket, the first will be used. If there are no pending
   connections, socket_accept() will block until
   a connection becomes present. If socket
   has been made non-blocking using
   socket_set_blocking() or
   socket_set_nonblock(), FALSE will be returned.
  
   The socket resource returned by
   socket_accept() may not be used to accept new
   connections. The original listening socket
   socket, however, remains open and may be
   reused.
  
   Returns a new socket resource on success, or FALSE on error. The actual
   error code can be retrieved by calling
   socket_last_error(). This error code may be passed to
   socket_strerror() to get a textual explanation of the
   error.
