composer autoload not work with global funtion [duplicate] - php

Question

I am trying to make my own mock MVC framework as a project. This is my first time using composer outside of using it for requiring dependencies for Laravel. The actual autoloading works well, but when I try to autoload the helpers.php something weird happens. The file is autoloaded(if I change the path of the file I get the file not found error) but the contents inside it are not. In another file I try to call any function from the helpers.php file and I get
Fatal error: Uncaught Error: Call to undefined function
This is the file structure of the example
composer.json
App
Utils
helpers.php
public
index.php
This is my composer.json file:
{
"name": "admin/projecttest",
"autoload": {
"psr-4": {
"Admin\\Projecttest\\": "src/",
"App\\": "App/"
},
"files": [
"App/Utils/helpers.php"
]
},
"minimum-stability": "dev"
}
The helpers.php
<?php
namespace App\Utils;
use Leonlav77\Frejmcore\helpers\DotEnv;
function config($config){
$config = explode(".", $config);
$file = $config[0];
$configFile = require "../config/$file.php";
return $configFile[$config[1]];
}
function env($key, $default = null){
(new DotEnv(__DIR__ . '../../.env'))->load();
return getenv($key) ? getenv($key) : $default;
}
function baseDir(){
return __DIR__ . "/../";
}
index.php (where I call the function from the helper)
<?php
require "../vendor/autoload.php";
var_dump(function_exists('baseDir'));
var_dump(baseDir());
from the function_exists I get false

As the user Foobar suggested the the problem was in the namespace of the helpers.php . Since it had a namespace the functions also had a namespace, so insted of baseDir() I needed to use App/Utils/baseDir().
The solution was to simply remove the namespace from helpers.php
