例子 1. stream_set_timeout() example |
<?php

fwrite($fp, "GET / HTTP/1.0\n\n");

注:
As of PHP 4.3, this function can (potentially) work on any kind of
stream. In PHP 4.3, socket based streams are still the only kind
supported in the PHP core, although streams from other extensions
may support this function.
This function was previously called as
set_socket_timeout() and later
socket_set_timeout() but this usage is deprecated.
See also
fsockopen() and
fopen().
