Jardis Repository

Part of Jardis — the Domain-Driven Design platform for PHP. You model your domain; Jardis generates the production-ready hexagonal code (DTOs, Command/Query handlers, repositories, persistence). This package is part of the open-source foundation that generated code runs on.

An implementation of the repository pattern for PHP: a generic CRUD repository operating on raw data — no entities, no ORM, just arrays in and out. Built-in read/write splitting routes queries to readers and mutations to the writer. Three primary key strategies cover autoincrement, generated integers, and application-supplied keys. It is the persistence building block that the repositories in generated Jardis code rely on.

Features

• Raw Data — arrays in, arrays out; no entity mapping, no hydration overhead
• Read/Write Splitting — queries automatically route to a dedicated reader; mutations go to the writer
• 3 PK Strategies — PkStrategy::AUTOINCREMENT, PkStrategy::INTEGER, PkStrategy::NONE for all insert patterns
• ConnectionPool Integration — accepts a ConnectionPoolInterface or a plain PDO instance
• Query Builder Support — findByQuery() accepts any DbQueryBuilderInterface for complex SELECT statements
• Exists Check — exists() avoids full row fetches when only presence matters
• Batch Delete — deleteAll() removes multiple rows in a single call
• Conditional Writes — optional $expected on update()/delete() guards against stale reads (optimistic concurrency); returns false when the row no longer matches
• Lazy Connection Initialization — reader and writer connections are opened only when first used

Installation

composer require jardissupport/repository

Quick Start

use JardisSupport\Repository\Repository;
use JardisSupport\Contract\Repository\PrimaryKey\PkStrategy;

$repository = new Repository($pdo);

// Insert a row — returns the new autoincrement id
$id = $repository->insert('orders', 'id', [
    'customer_id' => 42,
    'total'       => 199.99,
    'status'      => 'pending',
]);

// Fetch by primary key
$row = $repository->findById('orders', 'id', $id);

// Update
$repository->update('orders', 'id', $id, ['status' => 'confirmed']);

// Delete
$repository->delete('orders', 'id', $id);

Advanced Usage

use JardisSupport\Repository\Repository;
use JardisSupport\DbQuery\DbQuery;
use JardisSupport\Contract\Repository\PrimaryKey\PkStrategy;

// Read/write splitting via a connection pool
$repository = new Repository($connectionPool);

// Application-supplied UUID key (PkStrategy::NONE — no last-insert-id lookup)
$uuid = $uuidGenerator->generate();
$repository->insert('products', 'uuid', ['uuid' => $uuid, 'name' => 'Widget'], PkStrategy::NONE);

// Complex query via DbQuery builder
$query = (new DbQuery())
    ->select('o.id, o.total, c.email')
    ->from('orders', 'o')
    ->innerJoin('customers', 'o.customer_id = c.id', 'c')
    ->where('o.status')->eq('pending')
    ->and('o.total')->gte(100)
    ->orderBy('o.created_at', 'DESC')
    ->limit(20);

$rows = $repository->findByQuery($query);

// Batch delete
$repository->deleteAll('sessions', 'id', [101, 102, 103]);

// Existence check without fetching the row
if ($repository->exists('users', 'id', $userId)) {
    // ...
}

Conditional writes (optimistic concurrency)

public function update(
    string $table, string $pkColumn, int|string $id, array $values,
    array $expected = [],   // column => value the row must still carry; null => IS NULL
): bool;

public function delete(
    string $table, string $pkColumn, int|string $id,
    array $expected = [],
): bool;

$expected pins the write to the values a caller already read — one extra AND condition per column. If the row no longer carries those values, the statement touches 0 rows and the call returns false instead of silently overwriting a stale read.

// Two readers fetch the same row: ['status' => 'pending', ...]
$row = $repository->findById('orders', 'id', $id);

// Reader A writes first — the row still matches, write succeeds
$repository->update('orders', 'id', $id, ['status' => 'confirmed'], ['status' => 'pending']); // true

// Reader B writes second, unaware A already won — the row no longer matches
$repository->update('orders', 'id', $id, ['status' => 'cancelled'], ['status' => 'pending']); // false

• null in $expected maps to IS NULL, not = NULL.
• false means the row no longer carries the expected values — or the id doesn't exist. For a conflict check both are the same signal: the read this write was based on is no longer valid.
• $expected values must be scalar|null; an object or array throws InvalidArgumentException.
• An empty $values combined with a non-empty $expected throws InvalidArgumentException too — the existing "nothing to write" shortcut would otherwise skip the check silently and return true unchecked. Use exists()/findById() for a pure read-side check.
• MySQL note: rowCount() counts changed rows — an update that would set identical values reports 0. This doesn't fire for repositories built from changed-field diffs, but it's a caveat if $values is assembled differently.
