We bundled a lot of extension like bcmath, iconv, json, libxml, PDO, sqlite and more. You can see the complete list of extensions with a lot of other information in the phpinfo listing.
Currently we support local SQLite databases through these extensions: SQLite3, SQLite and PDO. MySQL support is planned for one of the next versions.
In the current version we don't have FTP or Dropbox because of Apple's restrictions. They don't allow code-executing apps to also import the code. We are currently working on a solution to allow importing files.
There is, however, an unofficial solution: iFunBox is a desktop software that allows you to upload/download files from iPhone/iPad directly, without the app's support.
