Paypal IPN - Altering a database?

[Minteh Fresh]

Hey guys, extremely curious as to how I'd go about using php to alter a mysql database via paypal.

Absolutely clueless when it comes to .php, so if anybody doesn't mind chuckin' me an inbox or maybe commenting here giving me a hand, I'd greatly appreciate it!

Thanks guys,

Minteh Fresh.

This is for SQLite however.
The queries you'll be using the most are

$result = $db -> query('SELECT * FROM user_steam WHERE steamID64 = ' . $profile);

This was made for a steam site where I store the steam user's STEAM number (76561198013370444) + their name (Digits) + some more info and that's the way I retrieve it.

And then you'll want to use the UPDATE function to make changes to their data after it's set.
(UPDATE `tablename` SET `rowname`= 'newcharacter' ... WHERE steamID64 = 76561198064470517 )
