Are there performance differences between using echo statements to output HTML versus concatenating HTML strings in PHP?

When outputting HTML in PHP, using echo statements can be more efficient than concatenating HTML strings. This is because echo directly outputs the content to the browser, while concatenating strings requires additional memory allocation. Therefore, for better performance, it is recommended to use echo statements when outputting HTML in PHP. 

// Using echo statements to output HTML
echo "<div>";
echo "<p>Hello, world!</p>";
echo "</div>";
