title: Get first file in directory PHP
body: <p>I want to get the first file in a directory using PHP.</p>
  
  <p>I am trying to make a function where the users on my website can change their profile picture. To show their profile picture on their profile page I want to get the first image in their profile picture folder. I want to get the image they have uploaded, regardless of the file type. I have made it so when they upload a new picture the old one will be deleted, so it will just be one file in the folder. How do i do this?</p>
