An active record is mapping a database entity to a PHP object. Spoken plainly, if you have a users table in your database, you can "translate" a row in that table to a User class and a $user object in your codebase. See basic example.
Let's assume you have the following table:
CREATE TABLE users (
id INTEGER PRIMARY KEY,
name TEXT,
password TEXT
);Now you can setup a new class to represent this table:
/**
* An ActiveRecord class is usually singular
*
* It's highly recommended to add the properties of the table as comments here
*
* @property int $id
* @property string $name
* @property string $password
*/
class User extends flight\ActiveRecord {
public function __construct($databaseConnection)
{
parent::__construct($databaseConnection, 'users', [/* custom values */]);
}
}Now watch the magic happen!
// for sqlite
$database_connection = new PDO('sqlite:test.db'); // this is just for example, you'd probably use a real database connection
// for mysql
$database_connection = new PDO('mysql:host=localhost;dbname=test_db&charset=utf8bm4', 'username', 'password');
// or mysqli
$database_connection = new mysqli('localhost', 'username', 'password', 'test_db');
// or mysqli with non-object based creation
$database_connection = mysqli_connect('localhost', 'username', 'password', 'test_db');
$user = new User($database_connection);
$user->name = 'Bobby Tables';
$user->password = password_hash('some cool password');
$user->insert();
// or $user->save();
echo $user->id; // 1
$user->name = 'Joseph Mamma';
$user->password = password_hash('some cool password again!!!');
$user->insert();
echo $user->id; // 2And it was just that easy to add a new user! Now that there is a user row in the database, how do you pull it out?
$user->find(1); // find id = 1 in the database and return it.
echo $user->name; // 'Bobby Tables'And what if you want to find all the users?
$users = $user->findAll();What about with a certain condition?
$users = $user->like('name', '%mamma%')->findAll();See how much fun this is? Let's install it and get started!
Simply install with Composer
composer require flightphp/active-record Head over to the documentation page to learn more about usage and how cool this thing is! :)
