title: Upload text file in PHP
body: <p>I would like to upload a .txt file and I found this code in w3schools. But this code only allows images to be uploaded and stored in a  local drive. How do I change this into a .txt file upload format? Thanks for the response. :)</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;body&gt;
  
  &lt;form action="upload.php" method="post" enctype="multipart/form-data"&gt;
      Select image to upload:
      &lt;input type="file" name="fileToUpload" id="fileToUpload"&gt;
      &lt;input type="submit" value="Upload Image" name="submit"&gt;
  &lt;/form&gt;

  <p>This is the PHP code:</p>
