PHP 'Call to undefined function' across two different includes?

I've got four PHP files that will form a simple template for my website:
- functions.php (with all of the main functions for the website - huge file)
- index.php (the main template file I'll be using, that will bring together the other three documents)
- header.php (header for the website)
- footer.php (footer for the website - this is where the problem occurs)

functions.php - a snippet. This function is simply on its own, not inside of a class or anything.

<?php
function LandingPageURL($Phrase, $LPID){
$LandingPageURL = "https://www.website.com/" . trim(strtolower(str_replace("d'","",str_replace(" ", "-", $Phrase)))) . "-" . trim($LPID) . "/";
}
?>

header.php - no relevant parts. But, I am able to use functions from the functions.php file fine from here.

footer.php - relevant parts included. Error occurs here on line 27.

echo '<li><a href="' . LandingPageURL($ar_CHANNELS[$ar_CHANNELS_POS][$v_CH_PHRASE],$ar_CHANNELS[$ar_CHANNELS_POS][$v_CH_LPID])

The $ar_CHANNELS* variables are simply values from an array that I have.

index.php - relevant parts included.
This is included at the top of the file:

<?php
require ($_SERVER['DOCUMENT_ROOT'] . "/" . "resources/nw/lib/includes/functions.php");
?>

This definitely works as I am calling other variables from functions.php, which are successful.
Further down the file, I include first the header.php file, then the footer.php file in identical ways:

require ($_SERVER['DOCUMENT_ROOT'] . "/" . "page/page-elements/header.php");
require ($_SERVER['DOCUMENT_ROOT'] . "/" . "page/page-elements/footer.php");

When the footer.php is included, and I load the webpage, I get the error message:

Fatal error: Call to undefined function LandingPageURL() in C:\Hosting\website\httpdocs\page\page-elements\footer.php on line 27

Is it something that I'm doing wrong, calling a function from another file that is included into my main index.php file? I made sure to use 'require', so that I knew that functions.php was being pulled into the index.php.

The functipns.php file has to be included inside footer.php if you want to use its functions there.

Rather embarrassingly, the whole problem was caused by not properly closing a preceding function.
