stream_set_timeout should be what you're looking for.
might look like this:
<?php
$fp = fsockopen("www.example.com", 80);
if (!$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 {
echo $res;
}
}
?>
-- from the manual:
http://us4.php.net/manual/en/function.stream-set-timeout.php
$res will hold the first 2,000 bytes of the result.
socket blocking would be another way, but the above one looks like exactly
what you're looking for
