First off remember that PHP pages are not limited to purely writing PHP code. The PHP code is only inside of the <?php and ?> tags. Anything outside of those tags would not be PHP and could be anything that you could normally write in an HTML file. With a standard PHP file that is not going to be used as an include, you will have html tags in the file.
The command echo is one of the ways PHP can output content. So, basically we used the opening <?php tag to indicate that were starting to use PHP code. Then, we echo a string “I am awesome!”, which you are. And of course, we end our only statement with a standard ;. Finally, we tell the server that we no longer want to use PHP code and we close it with the ?> tag.
