What is the difference between the original PHP code in a file and the "already executed code"?

The original PHP code in a file contains the actual PHP code that needs to be executed, while the "already executed code" refers to the output or result of running the PHP code. If you are seeing the "already executed code" instead of the original PHP code, it may be due to a server misconfiguration or a file extension issue. To fix this, ensure that your server is set up to interpret PHP code correctly and that your file has a .php extension.

<?php
// Your original PHP code here
echo "Hello, World!";
?>
