How can variables be utilized to control the positioning of echo output within HTML code in PHP scripts?

To control the positioning of echo output within HTML code in PHP scripts, variables can be used to store the HTML code and then echo the variables in the desired order. By manipulating the variables containing the HTML code, you can control where the output appears on the page.

<?php
// Define variables containing HTML code
$heading = "<h1>Welcome to our website!</h1>";
$paragraph = "<p>This is a paragraph of text.</p>";
$footer = "<footer>© 2021 Company Name</footer>";

// Output the variables in the desired order
echo $heading;
echo $paragraph;
echo $footer;
?>
