PHP DI and casting interface

I do not understand, for example I'm using php-di container,
I have ClassA and ClassB, both of them are implements Intreface1
And I'm creating objects of this two classes thru DI

Now when I'm injecting ClassA to the constructor I need inject exactly this class, which crate a dependency of this classA, not an Intreface1

Can I somehow say that this particular ClassA should implement intrefeca1 ?
In docs of PHP-DI I found

// mapping an interface to an implementation
'LoggerInterface' => DIcreate('MyLogger'),


But I do not understand how it works, LoggerIntreace it's just a string which maps this text to to the object

You can inject "by interface"

example with monolog and php-di, you say :

use MonologLogger;

use PsrLogLoggerInterface;
...
LoggerInterface::class => DIautowire(Logger::class)


and now in your constructor, you can inject

public function __construct(
PsrLogLoggerInterface $logger
)

$this->logger = $logger;
