Nothing is guaranteed to work. I just want to get this over with becuz i said i would before. If these functions do work properly (they do, i just mean doesnt get hacked), then they work great. It makes everything alot easier as far as i know. There is 1 example for each.
SELECT:
returns an array of all the field names as the key of the array, of the selected database file thing (usually a persons profile info)
INSERT:
returns the last id of the inserted thing. so, if you create a new profile, it will return the id of that added profile.
UPDATE:
it should return true or false. true if the update was successful, and false if it wasnt. i cant say for sure, but i am pretty sure that is what its supposed to return.
Notes:
keep error reporting off. these functions should work properly without errors anyway, but its just that i recently found out that if error reportings is on, it can show your database name and password. not becuz of these functions though, but just [a=http://stackoverflow.com/questions/6455018/why-does-pdo-print-my-password-when-the-connection-fails]read this[/url] for info. this is more of a random note, actually.
