Is it recommended to use loose return in a PHP file? When?

It's good practice to give a return in a simple PHP file example:

<?php

$config['teste'] = 123;

return $config;

I will explain better this file di / dependencias.php:

<?php


$container['daoExemplo'] = function ($c)
{
    return new ExemploDAO();
};

return $container;

I need to add all the anonymous functions contained in this file in a method, in case it will go through the entire directory di / example:

public function requireAllDependencies($directory)
{
    try {
        //setando o diretorio e o tipo de arquivo a ser carregado
        $dir = "{$directory}/*.php";

        //Percorrendo o diretorio e pegado o caminho dos aquivo
        foreach (glob($dir) as $filename)
        {
            //Adicionando as dependencias
            $dependencies = require $filename;
            $this->add($dependencies);
        }
    } catch(Exception $e) {
        echo "Erro ao tentar adicionar o arquivo: " . $e->getMessage();
    }
}

In this example would it make sense?
