[RESOLVED] require_once not getting variables from parent page

[lisa99]

Everywhere I look it seems I keep seeing that this should work...

//parent.php
$x=1
require_once("include.php");

//include.php
echo"$x";

This should display 1, right? It does not. I get no result.

Here's what I know...

1. I'm sure the include path is correct -- I can see other things from the included page.
2. I'm sure that my variables were set properly and actually do exist. I can echo them in the parent page before and after the require_once.
3. If I use var_dump within the required page, I get "NULL"
4. I have error reporting turned on and get no errors.

As a side note, I'm also not able to use URL vars when requiring a file.

require_once("include.php?x=$x");

gives the error "Failed to open stream...")

What am I missing?

###EDITED###

I am an idiot.

PHP was correct. I was wrong. Problem solved.

I the variable in the included page was capitalized and I didn't notice.

Sorry, guys.
