Echo Dropdown's Option Name Rather Than Its Value

I am attempting to echo the name of a selected dropdown rather than its value. I understand that echoing a dropdown's value can be achieved by implementing something such as:

$variable = $_POST['vehicleStyle'];
echo $variable;

where vehicleStyle is the <select> name.

However, I am not after the value I after the option's name.

Here is my PHP. I am extracting data from a XML Document where $k equals the option name and $v equals its value.

<html>
 <body>

  <?php
    $xml = file_get_contents('note.xml');
    $dom = new DOMDocument();
    $dom->loadXML($xml);
   ?>

    <form action="additionalinfo.php" method=POST>

     <select name="vehicleStyle">
      <option selected="selected">Choose style</option>
      <?php
        foreach ( $dom->getElementsByTagName('style') as $styletwo )   {
          $styleid = $styletwo->getAttribute("name");
          $styleData [$styleid]= $styletwo->getAttribute("id");;
            }
        foreach ($styleData as $k=>$v){
      ?>
    <option value='<?php echo $v;?>'><?php echo $k;?> </option>
     <?php
      }
     ?>
   </select>

   <br>
   <button class="button">Submit</button>
 </form>


 </body>
</html>

This outputs a dropdown containing two values: 'Audi=>292015` and 'BMW=>292016'. If I add

$variable = $_POST['vehicleStyle'];
echo $variable;

to my code, I get either 292015 or 292016 (whichever is selected). How can I echo the dropdown name, either Audi or BMW?

Thanks!

Solution

How about...

<option value='<?php echo $v . '|' . $k;?>'><?php echo $k;?> </option>

Then

$variable = $_POST['vehicleStyle'];
$variable = explode('|', $variable);

echo $variable[0];  //The "value"
echo $variable[1];  //The "text"

Might make some validation more difficult but it should get you what you need.
