use alcamo\conf\{Loader, XdgFileFinder}

$conf = (new Loader(new XdgFileFinder('foo')))->Load(
    [ 'default.ini', 'conf.ini' ]
);

Now $conf contains an array representing the contents of $XDG_CONFIG_HOME/foo/default.ini and $XDG_CONFIG_HOME/foo/conf.ini, where items in the latter replace items in the former with the same key, if $XDG_CONFIG_HOME is set. Otherwise, foo/conf.ini is searched as specified in the XDG Base Directory Specification

use alcamo\conf\{Loader as LoaderBase, XdgFileFinder as XdgFileFinderBase}

class XdgFileFinder extends XdgFileFinderBase
{
    public const SUBDIR = 'foo';
}

class Loader extends LoaderBase
{
    public const DEFAULT_FILE_PARSER_CLASS = XdgFileFinder::class;

    public const CONF_FILES = [ 'default.ini' ];
}

$conf = (new Loader())->Load('conf.ini');

This has exactly the same effect and may be more useful if configurations are loaded from the same subdirectory in many places in the code, in particular when there is a common basic configuration files plus specific configuration files.

use alcamo\conf\{Loader as LoaderBase, XdgFileFinder as XdgFileFinderBase}

class XdgFileFinder extends XdgFileFinderBase
{
    public const SUBDIR = 'bar';
}

$cacheFilename = (new XdgFileFinder(null, 'CACHE'))->find('data.json');

Now, $cacheFilename contains $XDG_CACHE_HOME/bar/data.json if $XDG_CACHE_HOME is set. Otherwise, the path is constructed as specified in the XDG Base Directory Specification. If the directory $XDG_CACHE_HOME/bar did not exist, it has been created automatically.
