PHP Files ECHO Statements Removal

I have 2 PHP files that use ECHO, and I want all ECHO statements to be removed while keeping the HTML and JavaScript structure intact.

If someone is experienced with this, please reach out.

here is a example

<?php

echo ' ';

if (count(get_included_files()) != 1) {
$_PAGE = getPageName();
include 'modals.php';

if ($rModal) {
} else {
echo ' <footer class="footer">' . "\r\n" . ' ';

if ($rMobile) {
} else {
echo ' <a href="#" class="scrollToTop" id="scrollToBottom"><button type="button" class="btn btn-info waves-effect waves-light"><i class="fas fa-caret-down"></i></button></a>' . "\r\n" . ' <a href="#" class="scrollToTop" id="scrollToTop"><button type="button" class="btn btn-success waves-effect waves-light"><i class="fas fa-caret-up"></i></button></a>' . "\r\n" . ' ';
}

echo ' <div class="container-fluid">' . "\r\n" . ' <div class="row">' . "\r\n" . ' <div class="col-md-12 copyright text-center">';
echo getFooter();
echo '</div>' . "\r\n" . ' </div>' . "\r\n" . ' </div>' . "\r\n" . ' </footer>' . "\r\n\t\t";
