Example #1 A stream_socket_shutdown() 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

?>
