Best way to store http.Post data

[MrSirLordSleepy]

I'm currently using http.Post to post the server's title and IP address into a file on my webserver (to track who is using my addon) but i've set it to create a new file per server to stop the file being overwritten everytime somebody new uses the addon.

This is the code i'm currently using, does anybody have any suggestions on how I can save all data to one file without it wiping all previous data when new data is posted?

<?php
$p = $_POST["p"];
$a = $_POST["a"];
$addon = $_POST["addon"];

$f = fopen("$p.html", "w");

fwrite($f, "$addon $p $a\n");

fclose($f);
?>

http.Post( "http:/hiddenurl/gmod/post.php", { addon = "My addon name", a = tostring(GetHostName()), p = game.GetIPAddress() }, function( result )
if result then end
end, function( failed )
end)

I've tried writing them all to one file but it wipes all previous data.

Thanks

This is more of a php question than a lua question but in your fopen you need to set the mode to 'a' instead of 'w'

PHP: fopen

You can also store the data via sql using things like pdo for php
