title: Upload image in different folder for different user_id
body: <p>I am new to PHP. I have made a user registration form which includes user_id, name, password, email, and also uploaded images from the user. I would like these images to be stored for different users in different folders.</p>
  
  <p>For example, if a user_id is "aa" then create a new folder name "aa" and the image is saved to the folder name "aa" and so on..</p>
