title: How to bold a variable?
body: <p>How can I have text within a php variable be bold??</p>
  
  <pre><code>function show_balance_header ($balance, $currency)
  {
      (string)$display_output = null;
      $display_output = fees_main::display_amount(abs($balance), $currency, true);
      return $display_output;
  }
  </code></pre>
  
  <p>I want to bold <code>$balance</code>. Is there an easy way or do I need to edit <code>display_amount</code>?</p>
  
  <p>I've tried doing this:</p>
  
  <p><code>"&lt;b&gt;".$balance"&lt;/b&gt;"</code> but this did not get the correct variable,</p>
  
  <p>thanks in advance!!</p>
