README

Piko Db Record is a lightweight Active Record implementation built on top of PDO.

It has been tested and works with the following databases:

• SQLite
• MySQL
• PostgreSQL
• MSSQL

Installation

It's recommended that you use Composer to install Piko Db Record.

composer require piko/db-record

Documentation

https://piko-framework.github.io/docs/db-record.html

Usage

First, ensure you have the necessary autoloading in place:

require 'vendor/autoload.php';

Define Your Model

Use the Piko\DbRecord, Piko\DbRecord\Attribute\Table, and Piko\DbRecord\Attribute\Column classes to define your model. For example:

use Piko\DbRecord;
use Piko\DbRecord\Attribute\Table;
use Piko\DbRecord\Attribute\Column;

#[Table(name:'contact')]
class Contact extends DbRecord
{
    #[Column(primaryKey: true)]
    public ?int $id = null;

    #[Column]
    public $name = null;

    #[Column]
    public ?int $order = null;
}

Setup Database Connection

Create a new PDO instance and set up your database schema:

// See https://www.php.net/manual/en/class.pdo.php
$db = new PDO('sqlite::memory:');

$query = <<<EOL
CREATE TABLE contact (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  name TEXT NOT NULL,
  `order` INTEGER
)
EOL;

$db->exec($query);

Perform CRUD Operations

Create

Create a new record and save it to the database:

$contact = new Contact($db);
$contact->name = 'John';
$contact->order = 1;
$contact->save();

echo "Contact id : {$contact->id}"; // Contact id : 1

Read

Retrieve records from the database:

$st = $db->prepare('SELECT * FROM contact');
$st->execute();
$rows = $st->fetchAll(PDO::FETCH_CLASS, Contact::class, [$db]);

print_r($rows); // Array ([0] => Contact Object(...))

// Load a single record by primary key:
$contact = (new Contact($db))->load(1);

var_dump($contact->name); // John

Delete

Delete a record from the database:

$contact->delete();
print_r($st->fetchAll()); // Array()
