How to access a property in the application's config?

Question

Yii

Hello. Can you please tell me if I specify in the config.php of the application Can I somehow get the value of 'var' in the application? Thanks in advance to all who respond.
'sendPusle' => ['var' => 'value']

Answer 1

In general, there are params
in the config for this:

$config = [
    // …
    'params' => [
        'sendPusle' => ['var' => 'value']
    ],
];

What does it have to do with it out of the box and put it in a separate params.php file,
but of course you can, but in fact params is implemented that way and it is for such things
