Call Helper Function for using it on Controller in Cakephp 3

call_helper_in_controller.php

<?php
namespace App\Controller;

use App\Controller\AppController;

// Use Link Helper Class
use App\View\Helper\LinkHelper;

/**
 * ProductCategories Controller
 *
 * @property \App\Model\Table\ProductCategoriesTable $ProductCategories
 */
class ProductCategoriesController extends AppController
{

    /**
     * Index method
     *
     * @return void
     */
    public function index()
    {
        // Instantiate LinkHelper
        $linkH = new LinkHelper(new \Cake\View\View());
        $link = $linkH->makeEdit('test', 'http://google.com');
        debug($link);
        
        $this->set('productCategories', $this->paginate($this->ProductCategories));
        $this->set('_serialize', ['productCategories']);
    }
    
}
  ?>

For me in cakephp 3 worked with

use Cake\View\Helper\NumberHelper;
