How to change date format in Joomla?

Question

CMS

The date in the database is written in the format 2016-12-05.
And on the site you need to display as 12/05/2016, that is, rearrange everything in places and through a dot.
The array is retrieved from the base:

<?php
defined('_JEXEC') or die;

class mod_remont_comments_helper
{
  public static function get_remont_comments()
  {
    $db = JFactory::getDbo();

    $query = 'SELECT * FROM #__remontel_comment';
    $db->setQuery($query);
    $remont_comments = $db->loadObjectList();
        return $remont_comments;

  }
}

Then it is output.

<?php foreach ($remont_comments as $remont_comment): ?>
<li class="reviews__item">
    <div class="reviews__block">
        <i><?php echo $remont_comment->date ?></i>
    </div>
</li>
<?php endforeach; ?>

Answer 1

echo implode(".", array_reverse(explode("-", $remont_comment->date)));

или

echo date("d.m.Y", strtotime($remont_comment->date));
