Are there any best practices or guidelines for making the currently active page link appear bold in a PHP-generated navigation bar?

To make the currently active page link appear bold in a PHP-generated navigation bar, you can use a conditional statement to check if the current page matches the link being generated. If it does, you can add a CSS class to make it bold. 

```php
<?php
$current_page = basename($_SERVER['PHP_SELF']);
$pages = array('index.php', 'about.php', 'services.php', 'contact.php');

foreach ($pages as $page) {
    if ($current_page == $page) {
        echo '<a href="' . $page . '" class="active">' . ucfirst(str_replace('.php', '', $page)) . '</a>';
    } else {
        echo '<a href="' . $page . '">' . ucfirst(str_replace('.php', '', $page)) . '</a>';
    }
}
?>
```

In the above code snippet, we first get the current page using `$_SERVER['PHP_SELF']` and then loop through an array of page links. If the current page matches the link being generated, we add the `active` class to make it bold. Otherwise, we just display the link as normal.
