Zend Framework: Accessing configuration data in application.ini

Lately, I haven’t been doing any Zend Framework related things. Although currently tied up with other stuff, I check the community from time to time. Today, I found this quick and useful tip from Akrabat.

Akra talks about how you can access your configuration that you have set in your application.ini file – your configuration file.

Since it is a short post, I will copy-paste everything here.

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.

Of course, the source is found here with all the comments from Akrabat’s readers.

  1. e.s.t says:

    Helpful! Thanks.

  2. If I remember correctly, you can retrieve configuration.ini (When you are using (zend_application)) application resources you can get with it

    $this->bootstrap = $this->getInvokeArg('bootstrap');

    but other I don’t remember other configuration samples… If I see again I will be post the code in here
