<?php
if (! function_exists('test_function')) {
 function test_function() {
  echo "I'm a custom helper function";
 }
}

2. Loading of auxiliary function files

Create a fileapp/Support/Helpers/, and load the file containing the custom functions:

<?php
$helpers = [
 ''
];
// Loadforeach ($helpers as $helperFileName) {
 include __DIR__ . '/' .$helperFileName;
}

3. Automatically load files in

/**/
{
 "autoload": {
  "classmap": [
   "database"
  ],
  "psr-4": {
   "App\\": "app/"
  },
  "files": [
   "app/Support/Helpers/"
