Show One Category on Post

Question

How do i go about making the code only show one category?

    <?php
  $categories = get_the_category();
  foreach($categories as $key => $category) {
    $url = get_term_link((int)$category->term_id,'category');
    $categories[$key] =
      "<dt><h1>{$category->name}</h1> </dt>" .
      "<dd>{$category->category_description}</dd>";
  }
  echo "<dl>\n" . implode("\n",$categories) . "\n</dl>";
?>

The Reason why am asking is that I have two category(s) on some of the posts but i only want to show one of them. Is there way to add it to the code above so it only shows one thanks.

Thank you for your question.

Try using the following code.

<?php
  $categories = get_the_category();
  if($categories[0]) {
    $url = get_term_link((int)$categories[0]->term_id,'category');
    $temp = "<dt><h1>{$categories[0]->name}</h1> </dt><dd>{$categories[0]->category_description}</dd>";
      echo "<dl>\n" . $temp . "\n</dl>";
  }
?>
