What are some best practices for incorporating dynamic content, such as language links, in PHP code?

When incorporating dynamic content like language links in PHP code, it's best practice to use variables to store the language options and generate the links dynamically based on user preferences or other factors. This allows for easier maintenance and scalability of the code. 

<?php
$languages = array(
    'en' => 'English',
    'es' => 'Spanish',
    'fr' => 'French'
);

$currentLanguage = 'en'; // Assume English is the default language

foreach($languages as $code => $name) {
    echo '<a href="?lang=' . $code . '"';
    if($code == $currentLanguage) {
        echo ' class="active"';
    }
    echo '>' . $name . '</a>';
}
?>
