Don't do that.

And if the OP is opening the file anyway, he might as well use
readfile() instead.

Well I got it to work, much thanks to Richard Lynch, but now everytime I
download a file, it is corrupt. For example, when I download small .rar
file, just to test, it is always corrupt ('Unexpected end of archive'). I
also cleared my browser cache just to be sure, but same problem.
Here is the code as it stands. I just can't get my head around why it
wouldn't be working as it is...
<?php
//ob_start();
//ob_end_flush();
//ob_implicit_flush(TRUE);
$rslogin = '';
$rspass = '';
$link = addslashes(trim($_POST['link']));
function cut_str($str, $left, $right)
{
$str = substr(stristr($str, $left), strlen($left));
$leftLen = strlen(stristr($str, $right));
$leftLen = $leftLen ? -($leftLen) : strlen($str);
$str = substr($str, 0, $leftLen);
return $str;
}
// Get the full premium link, and store it in $full_link after the
redirect. *Surely* there is an easier way to get redirections?
if(strlen($link)>0)
{
$url = @parse_url($link);
$fp = @fsockopen($url['host'], 80, $errno, $errstr);
if (!$fp)
{
$errormsg = "Error: <b>$errstr</b>, please try again later.";
echo $errormsg;
exit;

Thanks to anyone who has already helped, I hope some genius can spot an
obvious error, because this is just beyond me!
