Description
bool
stream_set_timeout ( resource stream, int seconds [, int microseconds] )
Sets the timeout value on stream,
expressed in the sum of seconds and
microseconds. Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.
When the stream times out, the 'timed_out' key of the array returned by
stream_get_meta_data() is set to TRUE, although no
error/warning is generated.
Пример 1. stream_set_timeout() example

$fp = fsockopen("www.example.com", 80);
if (!$fp) {
echo "Unable to open\n";
} else {
fwrite($fp, "GET / HTTP/1.0\r\n\r\n");
stream_set_timeout($fp, 2);
$res = fread($fp, 2000);
$info = stream_get_meta_data($fp);
fclose($fp);
if ($info['timed_out']) {
echo 'Connection timed out!';
} else {

Замечание:
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.
