如何将图像上传到父目录中的文件夹

Question

I have following directory structure.

 [root_folder]
   [admin]
       [assets]
          [images]
       [classes]
          upload.php
     index.php
   [assets]
       [images]
index.php

I want to upload images into root_folder > assets > images .

I tried below codes on index.php which is in admin folder.

root_directory > admin > index.php

<?php
require_once "classes/upload.php";

$upload_handler = new Upload_images();
if (isset($_POST['submit'])) {
    $folder_toUpload = 'assets/images/';
    $fileName = $_FILES['fileToUpload']['name'];
    $fileTemp = $_FILES['fileToUpload']['tmp_name'];
    $upload_handler->upload($folder_toUpload, $fileName, $fileTemp);
}
?>
<form action="" method="post" enctype="multipart/form-data">
     Select File:
     <input type="file" name="fileToUpload" />
     <input type="submit" value="Upload Image" name="submit" />
</form>

root_directory > classes > upload.php .

<?php
class Upload_images
{
    public function upload($folder_toUpload, $fileName, $fileTemp)
    {
        $target_path = $folder_toUpload . $fileName;
        if (move_uploaded_file($fileTemp, $target_path)) {
            echo $target_path;
        } else {
            echo "Sorry, file not uploaded, please try again!";
        }
    }
}

these codes work fine but it uploads images into root_direcory > admin > assets > images .

I want to upload images into root_directory > assets > images .

In PHP

<?php
require_once "classes/upload.php";

$upload_handler = new Upload_images();
if (isset($_POST['submit'])) {
    $folder_toUpload = '../assets/images/'; //or use this $_SERVER['DOCUMENT_ROOT'].'/assets/images/';
    $fileName = $_FILES['fileToUpload']['name'];
    $fileTemp = $_FILES['fileToUpload']['tmp_name'];
    $upload_handler->upload($folder_toUpload, $fileName, $fileTemp);
}
?>
