How can CSS classes be utilized instead of inline styles for highlighting text in PHP output?

To utilize CSS classes instead of inline styles for highlighting text in PHP output, you can define a CSS class with the desired text highlighting style in your stylesheet and then apply this class to the HTML elements containing the text you want to highlight. This separation of concerns between content (PHP output) and presentation (CSS) allows for better maintainability and reusability of styles.

<?php
$highlightedText = "This text will be highlighted";

echo '<p class="highlight">' . $highlightedText . '</p>';
?>
