php - How does a Zend controller action have access to Form subclass for instantiation? -


considering subclass of zend_form

class form_mine extends zend_form {     public function init()      {          //form       }

then in 

class minecontroller extends zend_controller_action {     public function formaction()     {       $form = new form_mine();     } }

how controller know of 'form_mine's existence in order instantiated?

i understand through zend_form's constructor function init() called setting form through chain or routing controller access 'form_mine'?

the class name significant. default, given class named my_form_mine, zend class in file: /library/my/form/mine.php. understanding handled autoloader: http://framework.zend.com/manual/1.12/en/zend.loader.autoloader.html
