Pragmatism in the real world

Accessing your configuration data that's stored in application.ini

Zend_Application will read the data in your application.ini and make it available from your bootstrap’s getOptions() method. It then sets the bootstrap as a parameter in the front controller. Note that the top level keys are all normalised to lowercase too.

You can then retrieve the options in a number of ways.

In the controller you can do this:

public function someAction()
$bootstrap = $this->getInvokeArg('bootstrap');
$options = $bootstrap->getOptions();

Outside of the controller you can do this:

$bootstrap = Zend_Controller_Front::getInstance()->getParam('bootstrap');
$options = $bootstrap->getOptions();

One downside is that $options is a nested array, and not a Zend_Config object. If you prefer to work with a Zend_Config object you need to create it yourself as Zend_Application discards the one it creates. The easiest way to do this is to create a new method in your bootstrap to create the Zend_Config object and store to the registry.

protected function _initConfig()
$config = new Zend_Config($this->getOptions());
Zend_Registry::set('config', $config);
return $config;

You can then get at your config data wherever you need it. Try not to depend too much on Zend_Registry keys though, as it can make testing harder.

  1. Hello
    Thanks for your post.
    Help me. How to access database ressources in application.ini and write to Zend_Registry ?

    Thanks a lot

  2. bin,

    protected function _initDatabaseRegistry()
    $db = $this->getResource("db");
    Zend_Registry::set('db', $db);
    return $db;



  3. Note that you can actually combine bootstrap's registry with zend registry (why having duplicates ?)

    protected function _initRegistry() { $this->setContainer(Zend_Registry::getInstance());

  4. And what about module configuration? Can we have /mymodule/configs/config.ini in which we can put the same options as in application.ini? e.g. resources.session., resources.mail. etc.

  5. Why do you return stuff from _initXXX() methods?
    I've seen it done in Zend's own documentation but haven't seen anything actually use those return values. Does that come into play in unit testing, maybe?
