title: php can not access content of an array
body: <p>It's a result from amazon order list.</p>
  
  <p>partial of <code>var_dump($order)</code> gave me this:</p>
  
  <pre><code>["PaymentMethodDetails"]=&gt; array(3) {
      ["FieldValue"] =&gt; array(1) {
          [0]=&gt; string(8) "Standard"
      }
      ["FieldType"]=&gt; array(1) {
          [0]=&gt; string(6) "string"
      }
      ["ListMemberName"]=&gt; string(19) "PaymentMethodDetail"
  }
  </code></pre>
  
  <p><code>var_dump($order-&gt;PaymentMethodDetails[0])</code> gave me this:</p>
  
  <p><code>string(8) "Standard"</code></p>
  
  <p>but <code>var_dump($order-&gt;PaymentMethodDetails[1])</code> gave me this:</p>
  
  <p><code>Undefined offset: 1</code></p>
  
  <p>How do I access the rest of the contents there inside[PaymentMethodDetails]?</p>
