How can PHP developers ensure that generated HTML is properly formatted and indented?

PHP developers can ensure that generated HTML is properly formatted and indented by using PHP's built-in DOMDocument class. This class allows developers to create a new HTML document, manipulate its structure, and output the formatted HTML. By utilizing methods like `formatOutput(true)` and `preserveWhiteSpace(false)`, developers can ensure that the generated HTML is correctly formatted and indented. 

<?php
// Create a new DOMDocument object
$dom = new DOMDocument();

// Load the HTML content into the DOMDocument
$dom->loadHTML($html_content);

// Set the formatting options
$dom->formatOutput = true;
$dom->preserveWhiteSpace = false;

// Output the formatted HTML
echo $dom->saveHTML();
?>
