    <?php foreach ($publicacoesIDrow2 as $IDr2): ?>

      <div class="col-12 col-md-6 col-lg-4 mb-3 mb-md-0">

        <div class="card">

          <div class="img-container">

            <a href="index.php?post=<?php echo $IDr2['title']?>"><img src="<?php echo $IDr2['capa']?>" alt="<?php echo $IDr2['alt']?>" class="card-img-top"></a>

          </div>

          <div class="card-body">

            <a href="index.php?post=<?php echo $IDr2['title']?>" class="card-title cardTitleLink"><h1 class="cardTitle"><?php echo $IDr2['title']?></h1></a>

            <p class="card-text text-muted"><?php echo $IDr2['text']?></p>

          </div>

        </div>

      </div>

    <?php endforeach; ?>

  </div>

</div>

As you can see i putted a LIMIT 4. I want it to display a different record every time the user refreshes a page or enters another page. How can i do it?
