Are there any potential pitfalls in using display:none to hide elements in PHP?

Using `display:none` in PHP to hide elements is not recommended because it only hides the element visually, but it still exists in the HTML structure and can be accessed by users or search engines. To properly hide elements in PHP, you should use PHP to conditionally output the element based on certain criteria.

<?php
$showElement = false; // Set this to true or false based on your criteria

if ($showElement) {
    echo '<div>This element is visible</div>';
}
?>
