What are some best practices for utilizing PHP to generate and display graphical elements on a webpage?

When utilizing PHP to generate and display graphical elements on a webpage, it is best practice to separate the PHP logic from the HTML markup by using a template system like PHP's built-in `include` function or a more robust templating engine like Twig. This helps to maintain clean and organized code, making it easier to manage and update in the future. 

<?php
// Define data to be used in the template
$data = [
    'title' => 'Welcome to my website',
    'content' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'
];

// Include the template file
include 'template.php';
?>
```

In the `template.php` file, you can use PHP to generate HTML elements based on the data passed in:

```php
<!DOCTYPE html>
<html>
<head>
    <title><?php echo $data['title']; ?></title>
</head>
<body>
    <div>
        <p><?php echo $data['content']; ?></p>
    </div>
</body>
</html>
