In what scenarios would it be more appropriate to use a definitions list instead of parsing HTML content for creating glossary links in PHP?

When creating glossary links in PHP, it may be more appropriate to use a definitions list instead of parsing HTML content when the glossary terms and their definitions are already known and fixed. This approach can be more efficient and easier to maintain compared to parsing HTML content to find and replace glossary terms with links. By using a definitions list, you can easily reference the terms and their corresponding definitions in a structured manner.

// Define an array of glossary terms and their definitions
$glossary = [
    'PHP' => 'Hypertext Preprocessor',
    'HTML' => 'Hypertext Markup Language',
    'CSS' => 'Cascading Style Sheets'
];

// Output a definitions list for the glossary terms
echo '<dl>';
foreach ($glossary as $term => $definition) {
    echo '<dt>' . $term . '</dt>';
    echo '<dd>' . $definition . '</dd>';
}
echo '</dl>';
