@JoshuaSWarren #phpworld Dependency Injection • Dependencies are injected into objects that need them • “Don’t call us, we’ll call you” • Instead of building an object in your class, it’s passed in via your constructor, automatically.

Slide 35 text

@JoshuaSWarren #phpworld Dependency Injection • Magento 2 uses the Constructor Injection pattern of DI • Automatic Dependency Injection • Handled in Magento 2 via XML files

 {
 $db = new DBHandler;
 $row = $db->query('SELECT price FROM products WHERE sku = ?', $sku);
 $formatter = new PriceFormatter;
 return $formatter->asDollars($row['price']);
 }
