Without defining the action attribute, form element WILL NOT send the request to any page via any method.

In addition, using button, probably would the server not send the request. Use input element instead.

If you really wish to send the data to the same page, use:

<form name="open_file" action="" method="GET">
<!--your link to this page in action attribute-->
  <select name="file" style="width:40%; font-size:20px;">
      <option value="A1" selected="selected" >A1</option>
      <option value="A2" >A2</option>
      <option value="A3" >A3</option>
  </select>
  <input type="submit" name="submit" value="UPLOAD" />
</form>

Plus, it is not a good practice to process form data after outputting HTML. Put the PHP code at the beginning of the document.

First, you have to define your form action and method like :

<form name="open_file" action="" method='GET'>
      <select name="file" style="width:40%; font-size:20px;">
          <option value="A1" selected="selected" >A1</option>
          <option value="A2" >A2</option>
          <option value="A3" >A3</option>
      </select>
      <button type="submit" name="submit">UPLOAD</button>
</form>
<!-- GET YOUR SELECT VALUES USING PHP -->

<?php 
    if(isset($_GET['file'])){
        $file = $_GET['file'];
        // Now you can use $file variable according to your code requirements
    }
?>
