InitORM DBAL

A small, dependency-free database abstraction layer for PHP. initorm/dbal gives you a thin, lazily-connecting PDO wrapper and a fluent result mapper — nothing more.

It is part of the InitORM stack, but it has no runtime dependencies and can be used on its own anywhere PDO can.

Highlights

• Lazy connections. No socket is opened until the first query.
• Driver-aware DSN building. MySQL/MariaDB, PostgreSQL, SQLite.
• Fluent result mapper.asAssoc(), asObject(), asClass(), asLazy(), asArray() / asBoth().
• Type-aware binding.bool → PARAM_BOOL, int → PARAM_INT, null → PARAM_NULL, everything else → PARAM_STR.
• In-memory query log for debugging hotspots.
• PSR-3 friendly logging. Pass any LoggerInterface, a callable, a file path, or anything with a critical() method.
• Transparent PDO forwarding. Unknown method calls are forwarded to the underlying PDO / PDOStatement, so lastInsertId(), beginTransaction(), closeCursor(), etc. all work directly on the wrapper.

Installation

composer require initorm/dbal

Requirements: PHP 8.0+ and the pdo extension, plus the driver extension for the database you target (pdo_mysql, pdo_pgsql, pdo_sqlite).

60-second quick start

useInitORM\DBAL\Connection\Connection;
$db = newConnection([
'driver' => 'mysql',
'host' => '127.0.0.1',
'port' => 3306,
'database' => 'shop',
'username' => 'app',
'password' => 'secret',
'charset' => 'utf8mb4',
]);
// Read$user = $db->query('SELECT id, name FROM users WHERE id = :id', ['id' => 42])
->asAssoc()
->row();
// Write$db->query(
'INSERT INTO users (name, email) VALUES (:name, :email)',
['name' => 'Alice', 'email' => 'alice@example.com']
);
$newId = (int) $db->lastInsertId(); // forwarded to PDO

Testing

composer install
composer test

The suite runs against SQLite in-memory and finishes in well under a second.

Upgrading from 1.x

See UPGRADE.md. The notable breaking changes are: PHP ≥ 8.0, src/ layout, PDO::ATTR_PERSISTENT defaults to false, rows() returns [] instead of null when empty, and bind() returns PARAM_BOOL for booleans.

Contributing

Issues and pull requests are welcome. Please:

1. Open an issue first if you intend to make a non-trivial change.
2. Make sure composer test is green.
3. Cover new behaviour with a test under tests/.

See the organisation-wide contribution guide for the full process.
