# pdo-document

Bit Badger Documents PHP implementation with PDO
This library allows SQLite (and, by v1.0.0-beta1, PostgreSQL) to be treated as a document database. It is a PHP implementation of the .NET [BitBadger.Documents](https://git.bitbadger.solutions/bit-badger/BitBadger.Documents) library.
## Add via Composer
`compose require bit-badger/pdo-document`
## Usage
Documentation for this library is not complete; however, its structure is very similar to the .NET version, so [its documentation will help](https://bitbadger.solutions/open-source/relational-documents/basic-usage.html) until its project specific documentation is developed. Things like `Count.All()` become `Count::all`, and all the `byField` operations are named `byFields` and take an array of fields.
