Parameters

string $key: The config key to get.

string $context: The path of either the directory in which to run Composer, or a specific configuration file (such as a particular package's `composer.json`) from which to read specific values.

Return value

string|null The output data. Note that the caller must know the shape of the requested key's value: if it's a string, no further processing is needed, but if it is a boolean, an array or a map, JSON decoding should be applied.
