How can PHP functions like ob_start() and ob_get_contents() be utilized to improve the efficiency of generating and saving dynamic HTML content?

When generating dynamic HTML content in PHP, using functions like ob_start() and ob_get_contents() can help improve efficiency by buffering the output. This means that the content is not immediately sent to the browser, allowing for manipulation and processing before final output. This can be especially useful when generating complex or large HTML content. 

<?php
// Start output buffering
ob_start();

// Generate dynamic HTML content
echo "<h1>Hello, World!</h1>";

// Get the buffered content
$html_content = ob_get_contents();

// Save the content to a file
file_put_contents('dynamic_content.html', $html_content);

// Flush and end the output buffering
ob_end_clean();
?>
