[phpiscool]

i am learning socket functions, but i was beaten by the first one...............

just a simple test

<?
$fp = fsockopen ("www.php.net", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br>\n";
}else echo "OK";

but:
Permission denied (13)

You're sure DNS lookups work for www.php.net on your server? Is your server behind a firewall?
