How can sprintf() be utilized to improve the readability and maintainability of HTML strings in PHP code?

When working with HTML strings in PHP code, it can quickly become messy and hard to read when concatenating variables and HTML tags together. Utilizing sprintf() can greatly improve the readability and maintainability of HTML strings by allowing you to separate the format template from the actual values being inserted. This makes it easier to visualize the final output and makes it simpler to make changes to the HTML structure. 

// Example of utilizing sprintf() for improved readability of HTML strings
$name = "John Doe";
$email = "john.doe@example.com";

$html = sprintf('
    <div>
        <p>Name: %s</p>
        <p>Email: %s</p>
    </div>
', $name, $email);

echo $html;
