sqlite databases won't open in anything else than PHP

I recently ported one of my PHP applications from MySQL to SQLite to make it easier to administrate. For some reason, I can access a the sqlite database from PHP an开发者_如何学JAVAd it works perfectly, but if I try to open it with something else, like sqlitemanager, or the sqlite firefox plugin, the database just seems blank, or it won't open it.

Any ideas?

Sqlite is available in (at least) two major versions, 2 and 3, which are incompatible. Maybe there is some mismatch between php and the other clients. E.g. the sqlite_ prefixed functions use the outdated version 2, while Sqlite3 is the proper php class for the current version 3.

php has the old sqlite lib by default I believe, unless you use PDO. perhaps its a db version issue.

It seems that the problem was PHP not closing the database at the end of the PHP script. As far as I know, PHP automatically closes mySQL connections at the end of a script. It doesn't do the same for sqlite. So you don't need to explicitly close mySQL connections, but because Sqlite is actually a file handle, you need to explicitly close it. Could somebody confirm this just so I'm sure?

PHP automatically closes SQLite connections as well. I agree with mtvee that it's probably the version. There's a very big difference between 2 and 3. PDO can do both, but takes 3 as default. You can use 2 and 3 with separate classes (without PDO) as well: new SqliteDatabase('db.sqlite2') and new Sqlite3('db.sqlite3'). I very much recommend using PDO (and the standard version 3).
