Add directory content, filename, to array is not working in WP [SOLVED]

Hi all.

I'm working on custom WP template and I'd like to add a variable that include a random image file name that comes from an array. I will then use this variable in <img> tag.

I have tried this php script outside WP website and it's working there.

The problem seems to be in the array part and what I think is that the scandir is not able to read or retrieve filelist from given path from $directory variable.

I'm starting to think that WP does not allow directory scan. What do you think?

Here is the code:

<?php
$directory = get_bloginfo('template_directory') . '/images/banners/header-images/';

$scanned_directory = array_diff(scandir($directory), array('..', '.'));

$rand_images = array_rand($scanned_directory, 1);

echo '<br><br>';
print_r($scanned_directory); //This command does not print the array to screen
?>

I had to use wp_upload_dir() instead of bloginfo() to be able to get the filelist.

<?php
$directory = wp_upload_dir();       

$scanned_directory = array_diff(scandir($directory['basedir'] . '/banners/header-images'), array('..', '.'));
$rand_images = array_rand($scanned_directory);
?>
