Introduction

Minimalist (but universal) database wrapper to rule them all (and to not choose).

Features

• Provide a generic API for handling database access across various implementations.
• Lightweight, framework adaptive and agnostic.
• Natively supports mysqli, pdo_mysql, pdo_sqlite drivers.
• Bridged implementations of zend-db, laravel and doctrine.
  • Access to Oracle, SQL-Server, PostgreSql,...
  • Allow to develop database portable libraries.
• Adhere to soluble programming standards.

Requirements

• PHP 7.1 optional ext-mysqli/PDO

For PHP 5.6+, 7.0+ or HHVM >= 3.9 look at version 1.3. For PHP < 5.6 take the 1.2 version

Documentation

• Manual in progress and API documentation available.

Installation

Instant installation via composer.

$ composer require soluble/dbwrapper

Quick start

Connection

Create an adapter from an existing Mysqli connection

<?php

use Soluble\DbWrapper;

$conn = new \mysqli($hostname,$username,$password,$database);
$conn->set_charset($charset);

$adapter = DbWrapper\AdapterFactory::createAdapterFromResource($conn);

Querying database

Execute SQL

<?php
$results = $adapter->query("select * from my_table");
foreach($results as $result) {
    echo $result['my_column'];
}

Get connection infos

Execute SQL

<?php
$connection = $adapter->getConnection();
echo $connection->getCurrentSchema();
echo $connection->getHost();

$resource = $connection->getResource();

API methods

AdapterFactory

The DbWrapper\AdapterFactory allows to instanciate an Adapter from en existing connection link or resource.

AdapterInterface

The DbWrapper\Adapter\AdapterInterface provides common operation on your database.

Resultset

The DbWrapper\Result\Resultset is can be easily iterated through a simple foreach loop. Additionnaly you can call the following methods :

ConnectionInterface

The DbWrapper\Connection\ConnectionInterface provides information about your connection

Supported databases

Native

soluble/dbwrapper supports natively :

For examples, see the native drivers doc

Userland implementations

Some of the supported databases can be (incomplete list) :

For examples, see the userland drivers doc

Motivations

Initially the reason behind the development of soluble/dbwrapper was to get a reliable and lightweight library to abstract the PDO_mysql and mysqli driver interfaces.

Later on, while developing some libraries, I feel the need for something more framework agnostic that could still be integrated easily into any modern framework. The userland drivers idea was born.
