use Symfony\Component\Config\Loader\LoaderInterface; class CustomLoader implements LoaderInterface { public function load($resource, $type = null) { // Load configuration data from a custom source } public function supports($resource, $type = null) { // Determine if this loader supports loading a particular resource type } }In summary, the LoaderInterface in Symfony\Component\Config\Loader package library provides a flexible way to load configuration data in PHP applications from different sources such as YAML, XML, or custom formats. The library also offers additional loader classes for different formats and can be extended by implementing the LoaderInterface in custom loader classes.
