PHP: Pass a variable to a file you are including?

Question

I am wondering if there is a way to pass a variable to a file you are including via include()?

I tried this but got an error:

include("header_alt.php?img=hey");

Is there a way to do that?

Thanks!

Just define your variable in the first file ; for instance, in temp.php :

<?php
$my_var = 10;

include 'temp-2.php';

die;
?>

And use it in the second file ; temp-2.php :

<?php

var_dump($my_var);

?>

And it should work : I'm getting this output, from temp-2.php :

int 10

The query-string syntax, using stuff like ?img=hey is used when you are requesting some data from a distant server (like when you are using your browser to surf on websites), not when including a file that is on the same server.
