How can a config.inc.php file be created for storing font color and style information in PHP?

To store font color and style information in a config file, we can create a config.inc.php file with PHP variables defining the font color and style values. This file can then be included in our PHP scripts to easily access and apply these values throughout our application.

<?php
// config.inc.php

$fontColor = 'black';
$fontStyle = 'italic';
?>
```

This config file can be included in other PHP scripts like this:

```php
<?php
// index.php

include('config.inc.php');

echo "<p style='color: $fontColor; font-style: $fontStyle;'>Hello, world!</p>";
?>
