Controlling Simultaneous Downloads from PHP

[subhachu]

Hi,
I would like to know, how to control the simultaneous downloads in PHP, say may be by trackin' from MySQL....

I need to allow only one IP to download a file... From my server... @ once.. Similar to ones found on the file-sharing sites!!!

Can any one help me???

Hi.

I'm not sure PHP would be able to do this by itself. Although, I must admit, I have not explored this area very well.

I suppose you could try something like:
[code=php]
<?php
$res = mysql_query("SE LECT IsDownloading FROM someTable");
$row = mysql_fetch_ass oc($res);
if($row['IsDownloading']) {
echo "Sorry, server is busy at the moment";
}
else {
mysql_query("UP DATE someTable SET IsDownloading = TRUE");
readfile("/path/to/file.ext");
mysql_query("UP DATE someTable SET IsDownloading = FALSE");
}
?>[/code]
But that might not be enough.
PHP might simply read the file into the output buffer and exit, even before the file is actually fully downloaded by the client.
