Dependency Injection in PHP vs Java

How to do Dependency Injection in PHP vs Java.

Plain PHP:

$helper_sales = new HelperSales();

Magento proprietary SPI:

// no type information!
$helper_sales = Mage::helper('sales');

Java / CDI :

private HelperSales helperSales;

Java / get bean from Spring context :

HelperSales helperSales = appCtx.getBean(HelperSales.class);

The Java examples apply to Scala as well, of course.

Still envy PHP?
