How can PHP be used to modify the HTML output in order to hide certain elements from the browser?

To hide certain elements from the browser using PHP, you can use conditional statements to determine when and which elements should be hidden. By dynamically generating the HTML output based on these conditions, you can control which elements are displayed to the user.

<?php
$hideElement = true;

if ($hideElement) {
    echo '<style>.element-to-hide { display: none; }</style>';
}

// HTML output
echo '<div class="element-to-hide">This element will be hidden if $hideElement is true.</div>';
?>
