......
?>

in the browser and get the contents of my document. Where to run and what to do? If .html is changed to .php then just a "white screen"

Answer 1

mv index.html index.php

Answer 2

If you have PHP installed and when you rename index.html to index.php you get a white screen, then some error has been fixed in PHP.
You need to look at the PHP log.

Reread the first lesson or what you are doing there.
