Simply ORM for the simply projects

The Database class is used for the database connection. This class is using the "configs/database.php" file with the next structure:

return [
    "host" => "localhost",
    "port" => 3306,
    "database" => "<database>",
    "username" => "<username>",
    "password" => "<password>"
];

Basic example

use FoxTool\Debra\EntityManager;
// User class, defined for example in the "app/Entity/User.php" file
use Debra\Entity\User;

// Create EntityManager instance
$em = new EntityManager();

// Set Model and return single object
$user = $em->setModel(User::class)->find(1);

// Display user login
echo $user->getLogin();

// Display the generated query text
$em->getQuery();

Examples:

Find record by ID

use FoxTool\Debra\EntityManager;
// User class, defined for example in the "app/Entity/User.php" file
use Debra\Entity\User;

$em = new EntityManager();
$user = $em->setModel(User::class)->find(1);

Find all records

use FoxTool\Debra\EntityManager;
// User class, defined for example in the "app/Entity/User.php" file
use Debra\Entity\User;

$em = new EntityManager();
$users = $em->setModel(User::class)->all();

The method all() returns array of objects of the User class

Find records by certain conditions

use FoxTool\Debra\EntityManager;
// User class, defined for example in the "app/Entity/User.php" file
use Debra\Entity\User;

$em = new EntityManager();
$users = $em->setModel(User::class)->where([
    "login = :login",
    "password = :password",
    "role = :role"
])->setParams([
    "login" => "bob",
    "password" => "12345678",
    "role" => "author"
])->get();

The method get() returns array of objects of the User class

Create new record

$em = new EntityManager();
$em->setModel(User::class);

$user = new User();
$user->setLogin('john');
$user->setPassword('12345678');
$user->setEmail('[e-mail]');
$user->setCreatedAt(date("Y-m-d H:i:s"));
$user->setUpdatedAt(date("Y-m-d H:i:s"));

$em->persist($user);
$em->save();

Update record

$em = new EntityManager();
$user = $em->setModel(User::class)->find(1);
$user->setLogin('john');
$user->setPassword('12345678');
$user->setEmail('[e-mail]');
$user->setCreatedAt(date("Y-m-d H:i:s"));
$user->setUpdatedAt(date("Y-m-d H:i:s"));

$em->persist($user);
$em->save();
