Super-light weight database engine to distribute part of tiny PHP script

Question

I am looking for a super-light weight open-source database engine (could be a library that mimics one) to be packaged part of a tiny PHP script distributed to people without sudo access. Basic CRUD, no need for any complicated implementations with string search, etc.

I found txtSQL (uses flat files, which I believe is the way to go) but hesitant to use it given the last time it was updated (2005-03).

Suggestions anyone?

Answer 1

sqlite gives you a platform-independent file format and is heavily regression tested and widely used. It is also available in PHP via SQLite3.

Answer 2

sqlite is about as light as you can get and it does everything via text files.
