CodePudding user response：

Try to usefunction_exists function

if (!function_exists('show_name')) {
    function show_name()
    {
        return 'Ahmed Emmam';
    }
}

CodePudding user response：

You should load the other files within the autoload field.

{
    "autoload": {
        "psr-4": { ... },
        "files": [
            "app/Helpers/Helper.php"
        ]
    }
}

CodePudding user response：

Aside from ensuring that your folders and files are located and named (case-sensitive) correctly, you likely want to add a namespace directive to your Helper.php file:

app/Helpers/Helper.php

<?php

namespace App\Helpers;

if (!function_exists('show_name')) {
    function show_name() {
        return 'Ahmed Emmam';
    }
}

You also need to update your web.php route to actually return a response:

routes/web.php

Route::get('test-helper' , function () {
    return show_name();
});

Ensure everything is loaded correctly using composer dumpautoload.
