In what ways can echoing output in a more structured manner improve the readability and maintainability of PHP code?

Echoing output in a more structured manner can improve the readability and maintainability of PHP code by separating HTML markup from PHP logic. This makes it easier to identify and modify the output without having to navigate through mixed PHP and HTML code. Additionally, using structured output methods like heredoc or concatenation allows for better organization and formatting of the output.

<?php
// Example of echoing output in a structured manner using heredoc
$name = "John";
$age = 30;

$output = <<<HTML
<div>
    <p>Name: $name</p>
    <p>Age: $age</p>
</div>
HTML;

echo $output;
?>
