Description

This is a simple class that can handle file uploads and returns JSON response.

It can take the $_FILES array as parameter and checks if a file with a given input name was uploaded successfully.

If the file was received, it is moved to the uploads directory.

The class creates an array with the response details and outputs the array JSON encoded so it is easier for the JavaScript to handle.

The details include a success message with a download link, and the name of the file that was stored. If the upload fails, an error message is returned.
