find one by symfony code example

Example 1: symfony findby

$repository = $this->getDoctrine()->getRepository(Product::class);

// look for a single Product by its primary key (usually "id")
$product = $repository->find($id);

// look for a single Product by name
$product = $repository->findOneBy(['name' => 'Keyboard']);
// or find by name and price
$product = $repository->findOneBy([
    'name' => 'Keyboard',
    'price' => 1999,
]);

// look for multiple Product objects matching the name, ordered by price
$products = $repository->findBy(
    ['name' => 'Keyboard'],
    ['price' => 'ASC']
);

// look for *all* Product objects
$products = $repository->findAll();

Example 2: symfony findoneby

$service = $repository->findBy(array('name' => 'Registration'),array('name' => 'ASC'),1 ,0)[0];
