When I include files in PHP, does it give me a blank screen?

Question

I am trying to include a heading at the top of my pages, but it gives me a blank screen. When I delete it, the PHP file starts up and shows the contents:

<?php
    include("header.php");
?>

What will go wrong?

Answer 1

There is probably an error in this file. try turning on display errors and reporting them:

ini_set('display_errors', 1);
error_reporting(E_ALL|E_STRICT);

Answer 2

Since you use enable, not require, a white screen means that you have a header.php error itself. Use the error report to narrow down the problem and eliminate the root of the problem.
