What are some best practices for formatting and organizing code when dynamically generating content in a web page?

When dynamically generating content in a web page, it's important to maintain clean and organized code for readability and maintainability. One best practice is to separate your PHP logic from your HTML markup by using a templating system like PHP's native `echo` function or a more robust solution like PHP's `include` function. Another best practice is to use proper indentation and spacing to make your code easier to read and understand.

<?php
// Example of dynamically generating content in a web page

// Define variables for dynamic content
$title = "Welcome to our website";
$content = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";

// Output HTML markup with dynamic content
echo "<h1>$title</h1>";
echo "<p>$content</p>";
?>
