..

Step 1: Declare in Vendor_ModuleName Block

You will use a block class of the module Vendor_ModuleName, then possibly inject the object of `\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory` in the constructor of the module’s block class.

    app/code/Vendor/ModuleName/Block/ProductCollection.php

add code this code 

<?php

    namespace Vendor\ModuleName\Block;

    class ProductCollection extends \Magento\Framework\View\Element\Template

    {    

        protected $_productCollectionFactory;

            

        public function __construct(

            \Magento\Backend\Block\Template\Context $context,        

            \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,        

            array $data = []

        )

        {    

            $this->_productCollectionFactory = $productCollectionFactory;    

            parent::__construct($context, $data);

        }

        public function getProductCollections()

        {

            $collection = $this->_productCollectionFactory->create();

            $collection->addAttributeToSelect('*');

            $collection->setPageSize(3); // fetching only 3 products

            return $collection;

        }

    }

    ?>

You can request the number of the product collection, that is a limited or unlimited number.

Step 2: Display product collection in phtml file

Print out the product collection in phtml file with the below code:

$productCollection = $block->getProductCollections();

    foreach ($productCollection as $product) {

        print_r($product->getData());     

        echo "<br>";

    }
