PHP Parse error: syntax error, unexpected T_OBJECT_OPERATOR
<p>I get this error when debugging:</p>

<pre><code>PHP Parse error:  syntax error, unexpected T_OBJECT_OPERATOR in order.php on line 72
</code></pre>

<p>Here is a snippet of the code:</p>

<pre><code>line 72: $purchaseOrder = new PurchaseOrderFactory-&gt;instance();
$arrOrderDetails = $purchaseOrder-&gt;load($customerName);
</code></pre>
