Yet another implementation of dependency injection container with PSR-11 compliant for PHP >8.0.
composer require please/containerThis example always returns a new instance of Mailer.
use Please\Container\Container;
use Please\Container\Support\Getter;
$container = new Container;
$container->bind(Mailer::class, function (Getter $get) {
return new Mailer::($get('user'), $get('password', 'qwerty')); // qwerty - default value
});
/** @var Mailer */
$mailer = $container->get(Mailer::class, [
'user' => 'admin',
// and password `qwerty` (default value)
]);This example always return a same time.
use Please\Container\Container;
$container = new Container;
$container->singleton('random', fn () => rand());
echo $container->get('random'); // 1234567890
echo $container->get('random'); // 1234567890You can find usage examples here.
You can bind any abstract aliases.
use Please\Container\Container;
$container = new Container;
$container->bind(Foo::class);
$container->get(Foo::class); // ok
$container->get('foo'); // error
// if you pass a class string
// it is also automatically bind as `Foo::class`
$container->bind('foo', Foo::class);
$container->get(Foo::class); // ok
$container->get('foo'); // ok
// array of aliases
$container->bind([Foo::class, 'foo', 'another-foo-alias'], Foo::class);
$container->get(Foo::class); // ok
$container->get('foo'); // ok
$container->get('another-foo-alias'); // okYou can bind any primitive data types.
$container->bind('foo', 'bar');
$container->bind('foo', 1337);
$container->bind('foo', 13.37);
$container->bind('foo', true || false);
$container->bind('foo', ['bar', 'baz']);
$container->bind('foo', new stdClass);
$container->bind('foo', fopen('php://stdout', 'r'));
$container->bind('baz', null);
$container->get('baz') // returns `baz`Generates a singleton instance of a class.
Singleton method always returns same value or instance like typical singleton pattern.
$container->singleton('timestamp', fn () => time());
// or use bind class and `shared` parameter
$container->bind('timestamp', fn () => time(), shared: true);Check if the container has a binding or instance for the given abstract.
$container->bind('foo', 'bar');
$container->has('foo'); // true
$container->has('baz'); // falseIf you really need to, you can use the container as a singleton.
use Please\Container\Container as BaseContainer;
use Please\Container\Support\Traits\Singleton;
class Container extends BaseContainer
{
use Singleton;
}
...
$container = Container::getInstance();
