ServiceManager / DI

Aura-Di, Laravel, Nette-DI, PHP-DI, Pimple, Symfony-DI, Zend-DI ...

ServiceLocator - DI

Provides integration for zend-di within zend-servicemanager

"zendframework/zend-servicemanager-di": "*"

ServiceLocator - build everything

public function build($name, array $options = null){ // We never cache when using "build" $name = isset($this->resolvedAliases[$name]) ? $this->resolvedAliases[$name] : $name; return $this->doCreate($name, $options);}

$serviceLocator->build(‘Customer’, [‘name’ => ‘Joe’]); // Joe

$serviceLocator->build(‘Customer’, [‘name’ => ‘Mike’]); // Mike

Never caches custom object builder through ServiceLocator

PluginManagerLocator - removed

You have to inject all your dependencies!

Middleware pipes are AWESOME!

Middleware pipes error handling
