Zend Framework 2 Module that provides some useful fundamental assets for reuse and convenience.

v0.2.0 2014-01-30 18:31 UTC


Version 0.1.0 created by Frank Hein and the mxc-commons team.

MxcGenerics is part of the maxence Open Source Initiative by maxence business consulting gmbh, Germany.


MxcGenerics provides generic classes and assets we use in development. Other modules from maxence rely on MxcGenerics.

Features / Goals

Main design goal of MxcGenerics is to encapsulate often used generic functionality.



Main Setup

By cloning project
  1. Clone this project into your ./vendor/ directory.
With composer
  1. Add this project in your composer.json:

    "require": {
        "mxc-commons/mxc-generics": "dev-master"
  2. Now tell composer to download MxcGenerics by running the command:

    $ php composer.phar update
Post installation
  1. Enabling it in your application.config.phpfile.

    return array(
        'modules' => array(
            // ...
        // ...

Package Contents

Directory: Form


Class derived from Zend\Form\Form enabled to trigger events.


Class derived from EventProviderForm which issues EVENT_PRE_BIND, EVENT_PRE_PREPARE and EVENT_PRE_VALIDATE.

Directory: Session


Class which creates a Zend\Session\SessionManager. Configuration options can be supplied through the 'session' config key.

Directory: Stdlib


GenericRegistry is a class comparable to Zend\Stdlib\AbstractOptions. It utilizes magic function to emulate a setter and getter for each value. Internally data is stored in an associative array.

$registry = new GenericRegistry();

echo $registry->getKneel();
echo $registry->getPray();

output: 72 42

GenericOptions is a class derived from GenericRegistry. On construction it expects an array structured like

$myOptions => array(
   'options' => array(
       'set1' => array(
           'value1' => 10,
           'value2' => 20,
        'set2' => array(
            'value1' => 32,
    'defaults' => array(
        'value1' => 1,
        'value2' => 2,

On construction GenericOptions get initialized with the values from the default section. If an (optional) option set is specified, these option set will be applied afterwards and extends/overrides the default options.

 $options = new GenericOptions($myOptions); 
 echo $options->getValue1();    //-- output 1
 echo $options->getValue2();    //-- output 2   

 $options = new GenericOptions($myOptions, 'set1'); 
 echo $options->getValue1();    //-- output 10
 echo $options->getValue2();    //-- output 20   

 $options = new GenericOptions($myOptions, 'set2'); 
 echo $options->getValue1();    //-- output 32
 echo $options->getValue2();    //-- output 2   

Collection of helper functions for strings. Currently the class contains one first single static member. formatVarExport is meant to make array var_export output look a little bit nicer.

Directory: Stdlib\Hydrator


Hydrator derived from Zend\Stdlib\Hydrator\ClassMethods. Overrides the __construct() parameter's default value for behaviour compatibility reasons regarding other hydrators.

Directory: ServiceManager


Class derived from Zend\ServiceManager\AbstractPluginManager. Associates Plugins with a set of GenericOptions.

 'my_plugin_options' => array(
     'plugin1' => array(
         //-- see GenericOptions above
     'plugin2' => array(
        //-- see GenericOptions above
 'my_plugins' => array(
    'invobables' => array(
        'plugin1' => 'My\Namespace\MyClass1',
        'plugin2' => 'My\Namespace\MyClass2',

Class derived from Zend\Mvc\Service\AbstractPluginManagerFactory. Applies setup options to the GenericPluginManager.

If you derive a plugin manager from GenericPluginManager and register it in the app's onInit you would implement the factory for your class like this:

class FirewallManagerFactory extends GenericPluginManagerFactory {

    const PLUGIN_MANAGER_CLASS = 'MxcFirewall\FirewallManager\FirewallManager';    

     * @see \Zend\ServiceManager\FactoryInterface::createService()
    public function createService(ServiceLocatorInterface $serviceLocator) {
        $config = $serviceLocator->get('Configuration');
        $this->setup = array(
           'plugin_options'    => 'firewall-options',
        $plugins = parent::createService($serviceLocator);

        return $plugins;    

If you want to create a plugin manager without global registration, you would create a factory like this (ListenerManager is the class derived from GenericPluginManager in this example):

class ListenerManagerFactory implements FactoryInterface {

     * @see \Zend\ServiceManager\FactoryInterface::createService()
    public function createService(ServiceLocatorInterface $serviceLocator) {
        $config = $serviceLocator->get('Configuration');
        $config = isset($config['firewall-listeners']) ? $config['firewall-listeners'] : null;
        $config = new Config($config);
        $plugins = new ListenerManager($config); 
        $plugins->setup(array('plugin_options' => 'firewall-listener-options'));
        return $plugins;

Directory: ServiceManager/Plugin


Base class of all Plugins maintained by GenericPluginManager. Derived PluginManagers should overwrite GenericPluginManager::isValid() according to the particular service classes you derive from AbstractPlugin.

AbstractPlugin handles service option setup through the GenericPluginManager.

Additionally, AbstractPlugin a generic helper function translateVars to replace strings in option values. Derived classes should overwrite getVars() according to their needs.

public function getRootDirectory() {
    return 'C:\';

public function getVars() {
    return array(
        '%rootDirectory% => $this->getRootDirectory(),
        '%myOtherReplacement% => 'test',

$value1 = '%rootDirectory%' . 'temp';
$value2 = '%myOtherReplacement%' . 'ing';
$value3 = 'myOption';

echo $this->translateVars($value1); //-- output: 'C:\temp'
echo $this->translateVars($value2); //-- output: 'testing'
echo $this->translateVars($value3); //-- output: 'myOption';

Example class demonstrating how to implement a plugin that allows overriding of it's options for the runtime of a particular method by parameters provided.

abstract class AbstractGenerator extends AbstractPlugin {

    protected $optionStack;

    public function generate($params, $options = null) {
        $this->options = $this->getActualOptions($params, $options);

        $result = $this->doGenerate($this->options);
        $reset = $this->options->getResetOptionsAfterRun();
        $this->options = $this->optionStack->pop();
        if ($reset) $this->resetOptions();
        return $result;     

    public function doGenerate($options) {

    protected function getOptionStack() {
        if (!$this->optionStack) {
            $this->optionStack = new SplStack();
        return $this->optionStack;

    public function resetOptions() {
        $this->optionStack = new SplStack();

We use an SplStack stack here to save the current options. Then, the parameters get merged with the options, thus overwriting/extending them. With the merged set of options we call doGenerate. Afterwards the original options get restored from the stack.

If the plugin options contain reset_options_after_run with value true, the plugin will be restored to its default setup and the option stack gets cleared.


We saw something like EventProviderForm in many modules.
