我看不到php包含页面

Question

I have an included php page into index.html.

<?php include "inc/header.php";?>

Dreamveawer cs5 is configured for viewing via wamp server.
On f12 I can't see this included file (only index.html is viewed, without includes)
If I open header.php itself - f12 - works well.
What could be the reason, please.

Answer 1

index.html is an HTML file, so PHP won't be parsed. Name the file index.php instead.
