Hehehe yes, but as I said in a later message, only my application will be
accessing this page (hopefully), and the problem is not on the sending
server (which has lots of bandwidth) but on the receiving client, where my
downloading is killing all its small bandwidth.
Ok, then there's not a real problem, but to get to your problem, you
could simple tell the script how many data to send per loop, and since
you're sleeping 1 second each loop, should this amount be the same as
the amount specified on the command line.
so, this should work the way you want
$sleep = $_GET['sleep'];
$fp=fopen($this->contentfile,"rb");
while(!feof($fp)){
print(fread($fp,1024*$speed));
flush();
ob_flush();
sleep(1);
}
fclose($fp);
