What is the purpose of the PHP Style Switcher in the context of CSS files and how does it function?

The purpose of the PHP Style Switcher is to allow users to change the CSS styles of a website dynamically. This can be useful for providing different themes or color schemes to users. The PHP Style Switcher functions by using PHP to dynamically change the link to the CSS file based on user input or preferences. 

```php
<?php
// Check if a style has been selected
if(isset($_GET['style'])){
    $style = $_GET['style'];
} else {
    $style = 'default'; // Default style
}

// Output the link to the CSS file based on the selected style
echo '<link rel="stylesheet" type="text/css" href="styles/' . $style . '.css">';
?>
```

In this code snippet, the PHP script checks if a style has been selected through the URL parameter 'style'. If a style is selected, it assigns it to the $style variable, otherwise, it defaults to 'default'. The script then outputs the link to the CSS file based on the selected style, allowing users to switch between different styles dynamically.
