variable $pageTitle undefined

For some reason, the variable $pageTitle is returning undefined up in the tab. No idea why. Here is the code.

suggest.php

<?php 
$pageTitle = "Suggest a Media Item";
include("inc/header.php"); ?>

<div class="section page">
  <h1>Suggest a media item.</h1>
</div>

<?php include('inc/footer.php'); ?>

header.php

<head>
    <title><?php echo $pageTitle; ?></title>
    <link rel="stylesheet" href="css/style.css" type="text/css">
</head>

Here is what it says up in the tab when I run this:

<br /> <b>Notice</b>: Undefined variable: pageTitle in <b>/home/...

That's all I could read

1) Are you sure you aren't looking at index.php but if so that you have assigned a value to $pageTitle before include("inc/header.php"); in index.php?

2) If that is all of your code for header.php you can't navigate to suggest.php from the start page since the links are included in the header. However you can add /suggest.php to the address bar to load the suggest page. For example mine looks like this:

http://port-80-0zodslm0uo.treehouse-app.com/suggest.php

Doing so you'll notice the tab displays "Suggest a Media Item" as you have in the code.

Thank you so much for your response. I have since resolved the issue although I never knew figured out exactly what the problem was :) I'm sure I probably misread some of that code when I pasted it in.

Exact same issue here.. did something change in PHP over the last 4 years? I can't be any more exact, and I even tried to tinker with it. It's just not taking into account the variable from the header on index. Welp.. moving on anyway. Maybe it'll clear up along the way.
