What are the potential pitfalls of using MySQL queries to determine visibility of HTML elements in PHP?

Using MySQL queries to determine the visibility of HTML elements in PHP can lead to performance issues and unnecessary database calls. It is more efficient to handle visibility logic within the PHP code itself rather than relying on database queries for such simple tasks.

// Instead of using MySQL queries to determine visibility, handle visibility logic in PHP

// Example of setting visibility based on a condition in PHP
$isVisible = true;

if ($isVisible) {
    echo "<div>This element is visible</div>";
}
