Got error while trying to run localhost website on cPanel - php

Question

I have been trying to switch my web app from localhost to a school server but it's telling me it cannot find the path:
Warning: require_once(/util/tags.php): failed to open stream: No such
file or directory in
/home/xiaoant/public_html/database_pizza/pizza/util/main.php on line
17
Fatal error: require_once(): Failed opening required '/util/tags.php'

<?php
// Start session to store user and cart data
session_start();
// Get the document root
$doc_root = filter_input(INPUT_SERVER, 'DOCUMENT_ROOT', FILTER_SANITIZE_STRING);
// Get the application path
$uri = filter_input(INPUT_SERVER, 'REQUEST_URI', FILTER_SANITIZE_STRING);
$dirs = explode('/', $uri);
$app_path = '/' . $dirs[1] . '/' . $dirs[2] . '/';
// Set the include path
set_include_path($doc_root . $app_path);
// Get common code
require_once('/util/tags.php');
require_once('/model/database.php');
// Define some common functions
function display_db_error($error_message) {
global $app_path;
include 'errors/db_error.php';
exit;
}
function display_error($error_message) {
global $app_path;
include 'errors/error.php';
exit;
}
?>

If you're using window and hosted it on a linux server Please check you path if it contain upper case letters directory names in linux is case sensitive unlike windows
Also you could list all the files in directory to check
'''$files1 = scandir($dir);
print_r($files1);
'''
And see if it there
