Przykład #1 socket_set_block() example
<?php
$socket = socket_create_listen(1223);
socket_set_block($socket);
socket_accept($socket);
?>
This example creates a listening socket on all interfaces on port 1223 and
sets the socket to O_BLOCK mode.
socket_accept() will hang until there is a connection
to accept.
