Q29. What is Bootstrapping?

Ans: Many PHP packages funnel server requests right into a unmarried (or few) PHP source record that units up the surroundings and configuration for the application, manages sessions and caching, and invokes the dispatcher for their MVC framework. They can do extra, however their essential process is to attend to the consistent wishes of every web page of a web application.

In our Blueprint for PHP Applications, we are able to have a center bootstrapper that gets all dynamic requests for an software and applies a template for software behavior that we are able to later enlarge. It will permit us to later customise the capability for every precise application.

Q30. What is zend engine?

Ans: Zend Engine is used internally via PHP as a complier and runtime engine. PHP Scripts are loaded into memory and compiled into Zend opcodes.

Q31. What is zend engine in PHP?

Ans: Zend engine is sort of a digital gadget and is an open supply, and is known for its position in automating the net the use of PHP. Zend is called after its builders Zeev and Aandi.

It is an open source project and freely to be had under BSD style license.

Q32. What is routing and how it is paintings?

Ans: Zend_Controller_Router_Rewrite is the standard framework router. Routing is the technique of taking a URI endpoint (that a part of the URI which comes after the bottom URL) and decomposing it into parameters to determine which module, controller, and action of that controller must receive the request. This values of the module, controller, action and different parameters are packaged right into a Zend_Controller_Request_Http object that is then processed with the aid of Zend_Controller_Dispatcher_Standard. Routing happens most effective once: whilst the request is first of all received and before the primary controller is dispatched.

Zend_Controller_Router_Rewrite is designed to permit for mod_rewrite-like capability the usage of natural PHP structures.

Using the ones, it is straightforward to delete particular kinds of facts afterwards (as an instance: "delete all cache data marked with a given tag").

The center of the module (Zend_Cache_Core) is ordinary, bendy and configurable. Yet, on your specific desires there are cache frontends that expand Zend_Cache_Core for comfort: Output, File, Function and Class.

Q35. Difference among Zend_Registry and Zend_Session?

Ans: The basic distinction among these items is the ‘scope’ wherein they're legitimate:

a) Zend_Registry : request scope

b) Zend_Session : consultation scope

a) Zend_Registry is used to save gadgets/values for the contemporary request. In brief, some thing that you decide to Registry in index.Hypertext Preprocessor can be accessed from different controllers/movements (because EVERY request is first routed to the index.Personal home page bootstrapper through the .Htaccess report). Config parameters and db parameters are typically prepped for worldwide use the usage of the Zend_Registry object.

B) Zend_Session clearly uses PHP sessions. Data saved using Zend_Session can be accessed in extraordinary/all pages. So, if you need to create a variable named ‘UserRole’ within the /auth/login script and want it to be handy in /auth/redirect, you would use Zend_Session.

Q36. When can we want to disable layout?

Ans: At the time of calling AJAX to fetch we want to disable format.

$this->_helper->layout()->disableLayout();

$this->_helper->viewRenderer->setNoRender(actual);

Q37. Where is the model in ZF’s MVC implementation?

Ans: The version thing can vary dramatically in obligations and records shop from one MVC application to the subsequent.

Q38. How to name two one of a kind views from equal motion?

Example1:

Public characteristic indexAction() 

If(circumstance)

$this->render(‘yourview.Phtml’);

Else

Index.Phtml;

Example2:

Public feature indexAction() 

Now for your index.Phtml you could have this declaration to call other view

$this->action(‘action name’,’controller name’,’module call’,array(‘parameter name’=>’parameter price’));

Q39. How to consist of css from controller and look at in zend.

Ans: From within a view file: $this->headLink()->appendStylesheet(‘filename.Css’);

From inside a controller: $this->view->headLink()->appendStylesheet(‘filename.Css’);

And then somewhere in your layout you need to echo out your headLink object:

headLink();?>

));

You must use a File decorator as opposed to the ViewHelper for the document detail, like so:

$element->setDecorators(array(

array('Errors')

));

This is particularly essential for corporations basing their commercial enterprise or merchandise on Zend Framework. The Zend Framework CLA enables to make certain that code and different IP in Zend Framework remains unfastened.

Q46. Should I sign an person CLA or a company CLA?

Ans: If you're contributing code as an person- and now not as a part of your activity at a agency- you should signal the person CLA. If you're contributing code as a part of your responsibilities as an employee at a organization, you must post a corporate CLA with the names of all co-people which you foresee contributing to the task.

Q47. Name a few Important issue in zend framework?

Ans: Gives the request & reponse methods by using the usage of its sub-lessons.

if ($consequences->isValid())

 

Zend_Session_Namespace

This is a easy proxy magnificence to use API into the Zend_Session managed $_SESSION Superglobal.

Q48. ZF  factor library and framework?

 

Ans: Zend Framework affords all of the components required for maximum net packages in a unmarried distribution. But Zend Framework components are also loosely coupled, making it easy to use only a few components in a web software- even along different frameworks! Using this use-at-will structure, we're imposing capabilities usually discovered in extra monolithic frameworks. In truth, we are currently operating on a tooling thing for the 1.8 release on the way to make it simpler to construct applications using ZF components, yet will not sacrifice the use-at-will nature of existing ZF components.

 

Q49. What is autoloader in Zend framework?

 

Ans: Auto loader is function that load all the item on begin up.

 

Q50. What is using Bootstrap in zend framework?
