       Example #1

	      A stream_socket_shutdown(3) example

	      <?php

	      $server = stream_socket_server('tcp://127.0.0.1:1337');
	      $client = stream_socket_client('tcp://127.0.0.1:1337');

	      var_dump(fputs($client, "hello"));

	      stream_socket_shutdown($client, STREAM_SHUT_WR);
	      var_dump(fputs($client, "hello")); // doesn't work now

	      ?>

	      The above example will output something similar to:

	      int(5)
