I am trying to access a variable $defaultPath from the php script that I have included.
However, when i am trying to echo the variable there is an error stating undefined variable. The php script is basically a nav bar (let's call it navbar.php) and this includes the helper.php which is where the variable $defaultPath is located. Moreover, the navbar.php is included in index.php in which index.php also includes helper.php. I used include_once to include the helper.php in both navbar.php and index.php but only index.php can echo the variable but not navbar.php
Here are the codes:
Navbar.php
<?php
include_once __DIR__ . '/../../helpers/helper.php';
echo $defaultPath . "</br>";
?>

Helper.php

function subview($file) {
$file = __DIR__ . '/../views/sub-views/'. $file;
include_once $file;
}
function cssPath($file, $defaultPath) {
$hrefPath = $defaultPath .'assets/css/'. $file;
return $hrefPath;
}
function jsPath($file, $defaultPath) {
$hrefPath = $defaultPath . 'assets/js/'. $file;
return $hrefPath;
}
function pageUrl($file, $defaultPath) {
$httpProtocol = !isset($_SERVER['HTTPS']) || $_SERVER['HTTPS'] != 'on' ? 'http' : 'https';
$url = $httpProtocol . '://' . $_SERVER['HTTP_HOST'] . $defaultPath;
if ($file !== 'index.php') {
$url .= 'views/' . $file;
}
return $url;
}
?>
Index.php
<?php
include __DIR__.'/helpers/helper.php';
?>
<!DOCTYPE html>

<?php subview('header.php') ?>

</div>
</section>
</main>
<?php subview('footer.php') ?>
</html>
Note: I am not trying to access the variable inside a function scope.
What I have tried:
I tried changing it back to include but error occurs because of duplicate functions.
I also tried echo-ing the the $defaultPath variable in index.php and there are no undefined error but when i try to do it in navbar.php it gives me undefined sadly
