title: Save Uploaded Text File to Web Server
body: <p>I have my users uploading a text file which then gets processed by my application. Once the processing is done, I would like to save a copy of this text file somewhere on my server for future reference. Currently, the uploaded text file stays in the PHP temp folder until it is closed by my app.</p>
  
  <p>What's a simple way to accomplish this?</p>
  
  <p>BTW, I'll need to know how to do this on my web server along with localhost (for testing).</p>
