title: Referencing the Compared Variable in PHP
body: <p>This feels like a really stupid question, but I've always wondered if I've been doing this wrong:</p>
  
  <pre><code>if($payment-&gt;shipping_state OR $payment-&gt;shipping_province)
      {
          $request['SHIPTOSTATE'] = isset($payment-&gt;shipping_state) ? $payment-&gt;shipping_state : $payment-&gt;shipping_province;
      }
  </code></pre>
  
  <p>Is there a keyword/an easier way to set <code>$request['SHIPTOSTATE']</code>to the variable which exists, since I already confirmed one of the two do in fact exist?</p>
  
  <p>Something like:</p>
  
  <pre><code>if ($payment-&gt;shipping_state OR $payment-&gt;shipping_province)
  {
    $var = $this;
  }
  </code></pre>
