Unsetting a configuration doesn't work as expected

[railken]

• Laravel Version: 6.18.40, 7.28.3, 8.6.0
• PHP Version: 7.2, 7.3, 7.4
• Database Driver & Version: mysql 5.7

Description:

After unsetting a config the default value doesn't work anymore

I think this happens because instead of unsetting the value with key, the value is set to null here

Steps To Reproduce:

$cfg = $this->app->get('config');
$this->assertEquals(3, $cfg->get('foo', 3));

$cfg->set('foo', 5);
$this->assertEquals(5, $cfg->get('foo'));

$cfg->offsetUnset('foo');
$this->assertEquals(7, $cfg->get('foo', 7)); // fails, $cfg->get('foo')  return null instead of 7

@driesvints Hi, this is not a support request.

Either is a bug or an intended behavior.

Please tell me why this has been moved to discussions.

Thanks

You are correct in your conclusion of why that is the case. It doesn't unset the key, it just sets it to null. The get uses Arr::get which uses Arr::exists to see if the key exists. Since the key exists it returns the value which is null.
