- #275 Enables plugin managers to accept as a creation context PSR Containers not implementing Interop interface
- Nothing.
- Nothing.
- Nothing.
- #268 Fixes ReflectionBasedAbstractFactory trying to instantiate classes with private constructors
- Nothing.
- Nothing.
- Nothing.
- Nothing.
-
#243 provides a fix to the
ReflectionBasedAbstractFactory
to resolve type-hinted arguments with default values to their default values if no matching type is found in the container. -
#233 fixes a number of parameter annotations to reflect the actual types used.
- Nothing.
- Nothing.
- #206 fixes an
issue where by callables in
Class::method
notation were not being honored under PHP 5.6.
-
#180 adds explicit support for PSR-11 (ContainerInterface) by requiring container-interop at a minimum version of 1.2.0, and adding a requirement on psr/container 1.0.
Zend\ServiceManager\ServiceLocatorInterface
now explicitly extends theContainerInterface
from both projects.Factory interfaces still typehint against the container-interop variant, as changing the typehint would break backwards compatibility. Users can duck-type most of these interfaces, however, by creating callables or invokables that typehint against psr/container instead.
- Nothing.
- Nothing.
- Nothing.
- #176 adds
the options
-i
or--ignore-unresolved
to the shippedgenerate-deps-for-config-factory
command. This flag allows it to build configuration for classes resolved by theConfigAbstractFactory
that typehint on interfaces, which was previously unsupported.
- Nothing.
- Nothing.
- #174 updates
the
ConfigAbstractFactory
to allow theconfig
service to be either anarray
or anArrayObject
; previously, onlyarray
was supported.
- #146 adds
Zend\ServiceManager\AbstractFactory\ConfigAbstractFactory
, which enables a configuration-based approach to providing class dependencies when all dependencies are services known to theServiceManager
. Please see the documentation for details. - #154 adds
Zend\ServiceManager\Tool\ConfigDumper
, which will introspect a given class to determine dependencies, and then create configuration forZend\ServiceManager\AbstractFactory\ConfigAbstractFactory
, merging it with the provided configuration file. It also adds a vendor binary,generate-deps-for-config-factory
, for generating these from the command line. - #154 adds
Zend\ServiceManager\Tool\FactoryCreator
, which will introspect a given class and generate a factory for it. It also adds a vendor binary,generate-factory-for-class
, for generating these from the command line. - #153 adds
Zend\ServiceManager\AbstractFactory\ReflectionBasedAbstractFactory
. This class may be used as either a mapped factory or an abstract factory, and will use reflection in order to determine which dependencies to use from the container when instantiating the requested service, with the following rules:- Scalar values are not allowed, unless they have default values associated.
- Values named
$config
type-hinted againstarray
will be injected with theconfig
service, if present. - All other array values will be provided an empty array.
- Class/interface typehints will be pulled from the container.
- #150 adds a "cookbook" section to the documentation, with an initial document detailing the pros and cons of abstract factory usage.
- Nothing.
- Nothing.
- #106 adds detection of multiple attempts to register the same instance or named abstract factory, using a previous instance when detected. You may still use multiple discrete instances, however.
- Nothing.
- Nothing.
- Nothing.
- #167 fixes how exception codes are provided to ServiceNotCreatedException. Previously, the code was provided as-is. However, some PHP internal exception classes, notably PDOException, can sometimes return other values (such as strings), which can lead to fatal errors when instantiating the new exception. The patch provided casts exception codes to integers to prevent these errors.
- Nothing.
- Nothing.
- Nothing.
- #136 removes
several imports to classes in subnamespaces within the
ServiceManager
classfile, removing potential name resolution conflicts that occurred in edge cases when testing.
- #103 Allowing
installation of
ocramius/proxy-manager
^2.0
together withzendframework/zend-servicemanager
. - #103 Disallowing
test failures when running tests against PHP

First stable release of version 3 of zend-servicemanager.
Documentation is now available at http://zend-servicemanager.rtfd.org
-
You can now map multiple key names to the same factory. It was previously possible in ZF2 but it was not enforced by the
FactoryInterface
interface. Now the interface receives the$requestedName
as the second parameter (previously, it was the third).Example:
$sm = new \Zend\ServiceManager\ServiceManager([ 'factories' => [ MyClassA::class => MyFactory::class, MyClassB::class => MyFactory::class, 'MyClassC' => 'MyFactory' // This is equivalent as using ::class ], ]); $sm->get(MyClassA::class); // MyFactory will receive MyClassA::class as second parameter
-
Writing a plugin manager has been simplified. If you have simple needs, you no longer need to implement the complete
validate
method.In versions 2.x, if your plugin manager only allows creating instances that implement
Zend\Validator\ValidatorInterface
, you needed to write the following code:class MyPluginManager extends AbstractPluginManager { public function validate($instance) { if ($instance instanceof \Zend\Validator\ValidatorInterface) { return; } throw new InvalidServiceException(sprintf( 'Plugin manager "%s" expected an instance of type "%s", but "%s" was received', __CLASS__, \Zend\Validator\ValidatorInterface::class, is_object($instance) ? get_class($instance) : gettype($instance) )); } }
In version 3, this becomes:
use Zend\ServiceManager\AbstractPluginManager; use Zend\Validator\ValidatorInterface; class MyPluginManager extends AbstractPluginManager { protected $instanceOf = ValidatorInterface::class; }
Of course, you can still override the
validate
method if your logic is more complex.To aid migration,
validate()
will check for avalidatePlugin()
method (which was required in v2), and proxy to it if found, after emitting anE_USER_DEPRECATED
notice prompting you to rename the method. -
A new method,
configure()
, was added, allowing full configuration of theServiceManager
instance at once. Each of the various configuration methods —setAlias()
,setInvokableClass()
, etc. — now proxy to this method. -
A new method,
mapLazyService($name, $class = null)
, was added, to allow mapping a lazy service, and as an analog to the other various service definition methods.
- Nothing
-
Peering has been removed. It was a complex and rarely used feature that was misunderstood most of the time.
-
Integration with
Zend\Di
has been removed. It may be re-integrated later. -
MutableCreationOptionsInterface
has been removed, as options can now be passed directly through factories. -
ServiceLocatorAwareInterface
and its associated trait has been removed. It was an anti-pattern, and you are encouraged to inject your dependencies in factories instead of injecting the whole service locator.
v3 of the ServiceManager component is a completely rewritten, more efficient implementation of the service locator pattern. It includes a number of breaking changes, outlined in this section.
-
You no longer need a
Zend\ServiceManager\Config
object to configure the service manager; you can pass the configuration array directly instead.In version 2.x:
$config = new \Zend\ServiceManager\Config([ 'factories' => [...] ]); $sm = new \Zend\ServiceManager\ServiceManager($config);
In ZF 3.x:
$sm = new \Zend\ServiceManager\ServiceManager([ 'factories' => [...] ]);
Config
andConfigInterface
still exist, however, but primarily for the purposes of codifying and aggregating configuration to use. -
ConfigInterface
has two important changes:configureServiceManager()
now must return the updated service manager instance.- A new method,
toArray()
, was added, to allow pulling the configuration in order to pass to a ServiceManager or plugin manager's constructor orconfigure()
method.
-
Interfaces for
FactoryInterface
,DelegatorFactoryInterface
andAbstractFactoryInterface
have changed. All are now directly invokable. This allows a number of performance optimization internally.Additionally, all signatures that accepted a "canonical name" argument now remove it.
Most of the time, rewriting a factory to match the new interface implies replacing the method name by
__invoke
, and removing the canonical name argument if present.For instance, here is a simple version 2.x factory:
class MyFactory implements FactoryInterface { function createService(ServiceLocatorInterface $sl) { // ... } }
The equivalent version 3 factory:
class MyFactory implements FactoryInterface { function __invoke(ServiceLocatorInterface $sl, $requestedName) { // ... } }
Note another change in the above: factories also receive a second parameter, enforced through the interface, that allows you to easily map multiple service names to the same factory.
To provide forwards compatibility, the original interfaces have been retained, but extend the new interfaces (which are under new namespaces). You can implement the new methods in your existing v2 factories in order to make them forwards compatible with v3.
-
The for
AbstractFactoryInterface
interface renames the methodcanCreateServiceWithName()
tocanCreate()
, and merges the$name
and$requestedName
arguments. -
Plugin managers will now receive the parent service locator instead of itself in factories. In version 2.x, you needed to call the method
getServiceLocator()
to retrieve the parent (application) service locator. This was confusing, and not IDE friendly as this method was not enforced through the interface.In version 2.x, if a factory was set to a service name defined in a plugin manager:
class MyFactory implements FactoryInterface { function createService(ServiceLocatorInterface $sl) { // $sl is actually a plugin manager $parentLocator = $sl->getServiceLocator(); // ... } }
In version 3:
class MyFactory implements FactoryInterface { function __invoke(ServiceLocatorInterface $sl, $requestedName) { // $sl is already the main, parent service locator. If you need to // retrieve the plugin manager again, you can retrieve it through the // servicelocator: $pluginManager = $sl->get(MyPluginManager::class); // ... } }
In practice, this should reduce code, as dependencies often come from the main service locator, and not the plugin manager itself.
To assist in migration, the method
getServiceLocator()
was added toServiceManager
to ensure that existing factories continue to work; the method emits anE_USER_DEPRECATED
message to signal developers to update their factories. -
PluginManager
now enforces the need for the main service locator in its constructor. In v2.x, people often forgot to set the parent locator, which led to bugs in factories trying to fetch dependencies from the parent locator. Additionally, plugin managers now pull dependencies from the parent locator by default; if you need to pull a peer plugin, your factories will now need to pull the corresponding plugin manager first.If you omit passing a service locator to the constructor, your plugin manager will continue to work, but will emit a deprecation notice indicatin you should update your initialization code.

It's so fast now that your app will fly!
- #60 adds
forward compatibility features for
AbstractPluingManager
and introducesInvokableFactory
to help forward migration to version 3.
- Nothing.
- Nothing.
- #46 updates the exception hierarchy to inherit from the container-interop exceptions. This ensures that all exceptions thrown by the component follow the recommendations of that project.
- #52 fixes
the exception message thrown by
ServiceManager::setFactory()
to remove references to abstract factories.
- #4 updates the
ServiceManager
to implement the container-interop interface, allowing interoperability with applications that consume that interface.
- Nothing.
- Nothing.
- #3 properly updates the
codebase to PHP 5.5, by taking advantage of the default closure binding
(
$this
in a closure is the invoking object when created within a method). It also removes several@requires PHP 5.4.0
annotations.
