Will flush() block until user recieve the data?

with ob_*() off

[Xuefer]

ob_end_clean();

$sock = fsockopen($ip, $port);

while (!feof($sock))
{
$s = socket_get_status($sock);
echo fread($sock, $s[unread_bytes']);
flush();// <<<---- will this block until the web client recieve the data?
}

or any better way to handle what i do? :)

It depends. The web server has a buffer, but if the data is much larger than the buffer, the server might sit there waiting for the data to drain. OTOH, if you have a caching proxy in front of your server, this probably won't be a problem.

The write is not completely synchronous, if that is what you're asking.

How large are your pages? If they aren't too big, don't worry.

it's not a page
it's for download
php connect to mIRC DCC port
get data from dcc and pass it to web user

changed to used functions in sockets.so
it works as expect :)
thx for replying
