The HTML page comments my php code, what should I do to make it display the php code as it is?

Question

PHP

Hello everyone, I ran into such a problem:
php code was not displayed on the page, I decided to look at her code, but it turned out that she comments php in this way.
<--?php echo 'text' ?-->
I don't know what it is and where exactly I made a mistake.
I have utf-8, I write via , and the local Denwer server.
I checked everything a hundred times, I can’t and that’s it. Help who knows.
