ZF3 correct place to put your api keys

Question

I guess I am doing it right because I can overrule the file by development mode but to be sure I ask. What is the right place to store API keys for services I installed through composer. For now I store the keys in the autoload directory inside local.php and receive them through service locator.

For example

$config  = $this->serviceLocator->get('Config'); 
var_dump($config['service_name_api']); // Returns api key

Is this the right way or should I use another way to access those properties?

Answer 1

Best place would be:

config/autoload/{config file name you want}.local.php

I suggest structure:

[
    'keystore' => [
        'api' => [
            // keys array
        ]
    ]
]

Repeat I suggest a structure above, you can create your own structure but anyway add

config/autoload/{config file name you want}.local.php.dist

file that has an example data on it.
