Echoing using PHP to an existing div

Question

I have a PHP function which returns this:

echo '<li>Welcome back.</li>' I would like that echo to be appended to an existing div on the html called <div id="messages"></div>

Is there any way of doing this with just simple echo or I should use Jquery?

Thanks!

Answer 1

if you are using php all you can do is to run your function inside the div

<div id="messages">
    <?php run_function_here();?>
</div>
