How to load multiple id's for products in magento 2 using objectManager?

Question

I want to load array(2,6,7) of products id's using objectManager and get details of the product. I found most of the Magento-1.9 solutions. Is there anything for Magento 2?

I found this,

<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
/** @var \Magento\Catalog\Model\ResourceModel\Product\Collection $productCollection */
$productCollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\Collection');
/** Apply filters here */
$collection = $productCollection->addAttributeToSelect('*')
            ->load();

foreach ($collection as $product){
     echo 'Name  =  '.$product->getName().'<br>';
}  
?>

but how to load my array product ids?

Try below code use in

 <?php
    $porIds=array(2,6,7);
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    /** @var \Magento\Catalog\Model\ResourceModel\Product\Collection $productCollection */
    $productCollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\Collection');
    /** Apply filters here */
    $collection = $productCollection->addAttributeToSelect('*')
                ->addFieldToFilter('entity_id', array('in' => $porIds));

                echo '<pre>';print_r($collection->getData());

Output

            [attribute_set_id] => 15
            [type_id] => simple
            [sku] => 24-MB04
            [has_options] => 0
            [required_options] => 0

            [updated_at] => 2017-11-03 11:21:57
        )

    [1] => Array
        (
            [entity_id] => 6

$products = $objectManager->get('Magento\Catalog\Model\Product')
            ->getCollection()

echo "<pre>";
print_r($products->getData());

$porductIds=array(2,6,7);
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$productCollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\Collection');
    $collectionByIds = $productCollection->addAttributeToSelect('*');
    $collectionByIds->addFieldToFilter('entity_id', array('in' => $porductIds));
    $collectionByIds->load();

    foreach ($collectionByIds as $collection) :
        echo "<pre>";
        print_r($collection->getName());
    endforeach;
