# Janitor tasks configuration files

You can optionally create Janitor tasks that hold some configuration in a separate configuration file, almost like [modules do](https://cherrycake.tin.cat/modules-guide#modules-configuration-file).

To do so, set the `isConfigFile` property of your [JanitorTask](https://cherrycake.tin.cat/reference/core-classes/janitortask) class like this:

```php
<?php

namespace CherrycakeApp;
    
class JanitorTaskMoviesUpdateImdbRating extends \Cherrycake\Janitor\JanitorTask {
    protected $isConfigFile = true;
    ...
}
```

Janitor task configuration files must be stored in the `config` directory of your app, and must have a name that matches the task name, even with upper and lowercase characters. For example, the configuration file for our `JanitorTaskMoviesUpdateImdbRating` task must be called `/config/JanitorTaskMoviesUpdateImdbRating.config.php`

Janitor task configuration files must declare a hash array named in the syntax `$<JanitorTaskName>Config`. For example, this the configuration file for our `JanitorTaskMoviesUpdateImdbRating` task:

```php
<?php

namespace Cherrycake;

$JanitorTaskMoviesUpdateImdbRatingConfig = [
    "imdbAPIKey" => "mfu9873n94hosdaonfo3289"
];
```

The values you set in the [JanitorTask::config](https://cherrycake.tin.cat/reference/core-classes/janitortask/janitortask-properties#config) property of your task class will be used if no configuration file is used, or if the configuration key has not been set in the configuration file.

To get a configuration value from a [JanitorTask](https://cherrycake.tin.cat/reference/core-classes/janitortask), use the [JanitorTask::getConfig](https://cherrycake.tin.cat/reference/core-classes/janitortask/janitortask-methods#getconfig) method, for example:

```php
$this->getConfig("imdbAPIKey");
```
