What are the best practices for handling context switching between PHP and HTML in code?

When handling context switching between PHP and HTML in code, it is best practice to separate the PHP logic from the HTML markup by using PHP opening and closing tags within the HTML code. This helps to maintain clean and readable code while ensuring that the PHP logic is executed correctly. Additionally, using functions or classes to encapsulate PHP logic can further simplify the code and improve maintainability.

<?php
// PHP logic to fetch data
$data = fetchData();

// HTML markup with PHP tags for context switching
?>
<div>
    <h1><?php echo $data['title']; ?></h1>
    <p><?php echo $data['content']; ?></p>
</div>
<?php
// More PHP logic or HTML markup can be added here
?>
