Hide a div if php echo content is empty

<div class="botontour"><a href="<?php echo $currentItem['video'];?
>">Video Tour 3D</a></div>

I want to hide the entire "botontour" div if the php echo has no return.

Solution 1:

in this case you can check if it's empty :

<?php
if (!empty($currentItem['video'])) {
?>
    <div class="botontour"><a href="<?= $currentItem['video'];?>">Video Tour 3D</a></div>
<?php
}
?>
