I get this error when debugging:

PHP Parse error:  syntax error, unexpected T_OBJECT_OPERATOR in order.php on line 72

Here is a snippet of the code:

line 72: $purchaseOrder = new PurchaseOrderFactory->instance();
$arrOrderDetails = $purchaseOrder->load($customerName);

Unfortunately, it is not possible to call a method on an object just created with new before PHP 5.4.

In PHP 5.4 and later, the following can be used:

$purchaseOrder = (new PurchaseOrderFactory)->instance();

In previous versions, you have to call the method on a variable:

$purchaseFactory = new PurchaseOrderFactory;
$purchaseOrder = $purchaseFactory->instance();

Note: The later is probably even more useful/wise even after you've upgraded to PHP 5.4 because those two lines can be better separated and there is less code containing a hard-encoded classname, here the name of the factory class PurchaseOrderFactory. This will make you more fluent maintaining the code over time.

Even if he used his code on PHP 5.4 that would generate a syntax error. – Muntashir Akon Oct 15 '15 at 13:48

change to as your syntax was invalid:

$purchaseOrder = PurchaseOrderFactory::instance();
$arrOrderDetails = $purchaseOrder->load($customerName);

where presumably instance() creates an instance of the class. You can do this rather than saying new

You can't use (it's invalid php syntax):

new PurchaseOrderFactory->instance();

You probably meant one of those:

// Initialize new object of class PurchaseOrderFactory
new PurchaseOrderFactory(); 

// Clone instance of already existing PurchaseOrderFactory
clone  PurchaseOrderFactory::instance();

// Simply use one instance
PurchaseOrderFactory::instance();

// Initialize new object and that use one of its methods
$tmp = new PurchaseOrderFactory();
$tmp->instance();
