What are the potential pitfalls of using if statements in PHP to control content visibility?

Using if statements in PHP to control content visibility can lead to code duplication and maintenance issues if the same condition needs to be checked in multiple places. To avoid this, consider using a function or variable to store the condition and reuse it throughout your code.

<?php
$isVisible = true;

if($isVisible) {
    echo "Content is visible.";
} else {
    echo "Content is hidden.";
}
?>
