Reading a value from application.ini

Question

I have a value that's defined in application.ini

conditions.time= 50

How can I read it in an zend action the zend way?

Answer 1

You can use Zend_Config_Ini

$config = new Zend_Config_Ini('my/ini/file.ini');
echo $config->conditions->time; // 50

Answer 2

The Application's Bootstrap.php has access to the application.ini using $this->getOptions() , you could store the value you want in your registry something like this:

  public function _initConditions()
  {
    $config = $this->getOptions();

    if (isset($config['conditions']))
    {

      $registry = Zend_Registry::getInstance();

      $registry->conditions = $config['conditions'];

    }
  }

You could then access your conditions using the registry, in much the same way that you set them here.

Answer 3

Here is my approach, which you can use anywhere in the application:

class My_Controller_Action_Helper_Options extends Zend_Controller_Action_Helper_Abstract
{
    /**
     * Options separator delimiterm e.g.
     * option.subkey or
     * option/subkey
     */
    const DELIMITER = '.';

    /**
     * Retrieve application options from bootstrap
     * 
     * @return array
     */
    public function getOptions()
    {
        $front = $this->getFrontController();
        $bootstrap = $front->getParam('bootstrap');
        if (null === $bootstrap) {
            throw new Exception('Unable to find bootstrap');
        }

        return $bootstrap->getOptions();
    }

    /**
     * Get array key if exists, otherwise returns null
     * 
     * @param array $values
     * @param string $key
     * @return mixed 
     */
    private static function _getValue($values, $key) 
    {   
        if (is_array($values) && isset($values[$key])) {

            return $values[$key];  
        } 

        return null;
    }

    /**
     * Get application option form bootstrap
     * 
     * @example
     * $options = Zend_Controller_Action_HelperBroker::getStaticHelper('options')
     * ->get('conditions.time', 'defaultvalue');
     * 
     * @param   string $section
     * @param   mixed $default
     * @return  Zend_Config
     */
    public function get($section = null, $default = null)
    {
        $value = $this->getOptions();

        if (null !== $section && is_string($section)) {
            if (false === strpos($section, self::DELIMITER)) {
                $value = $this->_getValue($value, $section);
            } else {
                $sections = explode(self::DELIMITER, $section);        
                foreach ($sections as $section) {
                    $value = $this->_getValue($value, $section);
                    if (null === $value) {

                        break;
                    }
                }
            }

        }

        if (null === $value) {

            return $default;
        }

        return $value;
    }

    /**
     * @param   string $section
     * @param   mixed $default
     * @return  Zend_Config
     */
    public function direct($section = null, $default = null)
    {
        return $this->get($section, $default);
    }
}

Answer 4

Here is an action helper for that :

class My_Controller_Action_Helper_Config
    extends Zend_Controller_Action_Helper_Abstract
{
    /**
     * @return array
     */
    public function direct()
    {
        $bootstrap = $this->getActionController()->getInvokeArg('bootstrap');
        $ns = strtolower(trim($bootstrap->getAppNamespace(), '_'));
        return $bootstrap->getOption($ns);
    }
}

You have to put your application namespace as a prefix :

; application.ini
My.conditions.time= 50

You can use it in a controller like this :

$config = $this->_helper->config();
$this->view->time = $config['conditions']['time'];

Answer 5

You might be able to use getenv('conditions.time')

Answer 6

PHP有一个parse_ini_file（）函数。
