Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include, or require, functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.

Won’t this:

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

include two carriage-return whitespace characters, one at the end of each closing PHP tag, which might cause the issue with the header output?

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

would eliminate that as a cause. Also have a look at either mysqli or PDO methods of accessing data - the old-style MySQL calls are deprecated so for new code, you shouldn’t really use them.

Are you 100% certain? Whitespace can not always be easily “seen”. As droopsnoot said, CR, LF, NL and even BOM can cause a “headers already sent”.

Does your text editor have a “show symbol” or equivalent option?

Also check files you include at the beginning (config.php, header.php).
They shouldn’t contain any output too.

Yes, header.php is probably the issue. Move it down below header("location: ← be sure there is a space here.

header("location: student-list.php?id=1");
include "header.php";
