1 :: Do you know what is the way in which the HTML can be used to form elements?
- The form elements can be customized using the decorators and using the Zend_Form for the rendering of the output.
- The description decorator can be used to have an instance running that allow the HTML to create the form elements.
- The turning of escape characters is required for the output of the decorator and it can be represented as shown below:
$element->setDecorators(array(
array('ViewHelper'),
array('Description', array('escape', false)),
array('Errors'),
array('HtmlTag', array('tag' => 'dd')),
array('Label', array('tag' => 'dt')),
));
- The element can be set to use the description by adding the extra HTML to this and it can be done using this:
$element->setDescription('<strong>Hello World</strong>');

2 :: Explain what is the procedure to see that the optional file is detected?
- There is a use of receive() method that returns true for the file element which is not required.
- The file can be neglected when using the method mentioned above, as soon as the file gets opened it detected.
- The method returns the false in case of any error or the file hasn’t been copied or uploaded directly.
- There are other methods used to provide the detection of the file using the elements in normal HTML file.
- The methods can detect the file and provide the tools to make the file being detected.

3 :: How to write a program that performs the calculations using the SQL function?
- The SQL functions are used to perform the calculations of the statements using the Zend_Db_Select command.
- The expression needs to have parentheses and the command that is given as Zend_Db_Select need to provide the statement appropriately.
- The Zend_Db_Expr is used to explicitly create the expressions that are given below:
$select = $db->select()
->from(array('p' => 'products'),
array(
'product_id',
'cost_plus_tax' => new Zend_Db_Expr('p.cost * 1.08'),
));

));
4 :: Can you explain what is the difference between Zend_Auth and Zend_Acl?
- Zend_Auth provides the authentication protocol for the users using many methods whereas; Zend_Acl is used for authorization purpose.
- Zend_Auth uses the methods like LDAP, OpenID and HTTP to provide the authentication, whereas Zend_Acl uses Access Control List for authorization.
- Zend_Auth provide the authentication in the form of verifying and providing the credentials for the user’s system, whereas Zend_Acl uses list of roles that is being implemented only those who are authorized to it.
- Zend_Auth provides an environment to the system through which user who is authenticated for use, whereas Zend_Acl performs some operations on the specific resources that need to be written on the system.
- Zend_Auth supports the authentication platforms features, whereas Zend_Acl supports the advanced definitions with features of multiple inheritance and other similar features.

5 :: Tell me what are the ways in which the file can be detected as being uploaded or not?
- There are certain functions used for the detection of the file and check whether the file is being uploaded properly or not.
- The use of isUploaded() function with the pre-defined parameters are used to check and it returns the boolean result.
- The use of getFileName() method is used to provide the latest releases of the file and returns the NULL.
- The use of getFileInfo() provides a way to make an empty file key that can be used to check whether the file is being uploaded or not.
- The flag is set for the isUploaded() method to false that allow the detection to be made easy.

6 :: Do you know what is the use of Zend framework?
- Zend framework is a robust framework that provides the components used by the web applications.
- It provides inbuilt libraries and functions to make the programming and integration easier.
- Zend framework consists of loosely coupled components that can be used to easily integrate in an application.
- It is used for the web application that uses lots of functions and libraries without writing much of the coding.
- It provides tools that can be used to have the standalone component based architecture.

7 :: Tell me what is the function of model in MVC architecture?
- MVC is made up of model, view and controller components to, represents the data in the architectural form.
- The model component can vary from one requirement to another for MVC application.
- The function model represents the application that has the abstract processing of the components.
- It uses the zend framework that defines MVC architecture at one place and allow the applications to use it.
- It is having the model interface, class and other components that used to identify the value and provide the limitations on the use.

8 :: How to write a program to show the function of action helper?
- Action helper is used to create the application and instantiate the object of it using the Zend_View.
- The object is used and stored using the ViewRenderer’s property that creates an instance and provides more options.
- It includes the dispatch process before any action is being dispatched from the view and the example code is given as:
if (!isset($viewRenderer->view)) {
$viewRenderer->initView();
}
$view = $viewRenderer->view;

$view = $viewRenderer->view;
9 :: Explain what is the function of action helper in Zend?
- Zend allows the creation of application using the framework that provides MVC architecture.
- The action helper is used to instantiates and store the object i.e Zend_View and other objects that are related to view.
- It also provides ways to inject the instantiation process in different objects by the help of action helper.
- The view object is stored in the view property provided by the action helper and a view instance is created using this.
- ViewRenderer instance is being created using the action helper function and it allows creating sync between all the objects.

10 :: How to write a program to retrieve the view object within plugin?
- Zend uses the framework that allows easy retrieving of the object within the arbitrary code.
- It uses the action helper and other class methods to view the object within the plugin.
- The method ViewRenderer() is used by default in the zend framework to view and render the components.
$viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer';
$view = $viewRenderer->view;
- It uses the action helper and other class methods to view the object within the plugin.
