    <title>Zend_Application Quick Start</title>

    <para>
        There are two paths to getting started with
        <classname>Zend_Application</classname>, and they depend on how you start your
        project. In each case, you always start with creating a
        <classname>Bootstrap</classname> class, and a related configuration file.
    </para>

    <para>
        If you plan on using <classname>Zend_Tool</classname> to create your project,
        continue reading below. If you will be adding
        <classname>Zend_Application</classname> to an existing project, you'll want to

        <title>Using Zend_Tool</title>

        <para>
            The quickest way to start using <classname>Zend_Application</classname> is to use
            <classname>Zend_Tool</classname> to generate your project. This will also create
            your <classname>Bootstrap</classname> class and file.
        </para>

        <para>
            To create a project, execute the <command>zf</command> command (on *nix systems):

        <programlisting language="sh"><![CDATA[
% zf create project newproject

        <programlisting language="dos"><![CDATA[
C:> zf.bat create project newproject

            First, create your <classname>Bootstrap</classname> class. Create a file,

            Now, create your configuration. For this tutorial, we will use an

        <para>
            You may note that the application environment constant value looks
            for an environment variable "APPLICATION_ENV". We recommend setting
            this in your web server environment. In Apache, you can set this
            either in your vhost definition, or in your <filename>.htaccess</filename>
            file. We recommend the following contents for your
            <filename>public/.htaccess</filename> file:

        <para>
            If you followed the directions above, then your bootstrap class
            will be utilizing a front controller, and when it is run, it will
            dispatch the front controller. However, in all likelihood, you'll
            need a little more configuration than this.

        <para>
            In this section, we'll look at adding two resources to your
            application. First, we'll set up your layouts, and then we'll

        </para>

        <para>
            One of the standard resources provided with
            <classname>Zend_Application</classname> is the "layout" resource. This
            resource expects you to define configuration values which it will
            then use to configure your <classname>Zend_Layout</classname> instance.
        </para>

        <para>
            To use it, all we need to do is update the configuration file.

            <filename>layout.phtml</filename> within that directory. A good starting
            layout is as follows (and ties in with the view resource covered
            next):

            At this point, you will now have a working layout.

        <para>
            Now, we'll add a custom view resource. When initializing the view,
            we'll want to set the <acronym>HTML</acronym> DocType and a default value for the title
            to use in the <acronym>HTML</acronym> head. This can be accomplished by editing your
            <classname>Bootstrap</classname> class to add a method:
        </para>

        <programlisting language="php"><![CDATA[
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initView()
    {
        // Initialize view
        $view = new Zend_View();
        $view->doctype('XHTML1_STRICT');
        $view->headTitle('My First Zend Framework Application');

        // Add it to the ViewRenderer
        $viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper(
            'ViewRenderer'
        );
        $viewRenderer->setView($view);

        // Return it, so that it can be stored by the bootstrap
        return $view;
    }
}
]]></programlisting>

        <para>
            This method will be automatically executed when you bootstrap the
            application, and will ensure your view is initialized according to
            your application needs.
