helper error

[pakuningratan]

I got this error when use helper on my project:
Fatal error: Cannot declare class CustomHelper, because the name is already in use in G:\laragon\www\sipka\app\helpers\CustomHelper.php on line 3

This my helper
\app\helpers\CustomHelper.php

<?php 
class CustomHelper {
    public static function hello($text) {
        // perform date formatting operations
        return 'haloooooooooo '.$text;
    }
}
?>

controller
app\controllers\jadwalController.php

<?php
namespace App\Controllers;
 
use App\Helpers\CustomHelper;
 

class JadwalController extends Controller
{
    public function index()
    { 
        $text = 'bla bla bla bla';

        $halo = CustomHelper::hello($text);
        echo $halo;
    }
}

please give me suggestion, thanks

Hi @pakuningratan I'm not sure why it's saying your CustomHelper class already exists, maybe it's defined somewhere else in your code. However, I noticed that you left out the namespace in your helper. namespace App\Helpers;

If the class is non existent it is then it's because the namespace is missing or the namespace does not follow the defined PSR standard i.e small case for the folders etc
