What are some best practices for formatting PHP outputs to avoid breaking the layout of a webpage?

When outputting PHP content within HTML, it's important to ensure that the PHP content doesn't break the layout of the webpage. One way to achieve this is by properly formatting the PHP outputs with appropriate HTML tags and CSS styling. Using functions like `echo` or `print` within HTML tags can help maintain the structure of the webpage.

<?php
  // Example PHP code snippet with proper formatting
  $name = "John Doe";
  echo "<p>Hello, $name!</p>";
?>
