It provides services to end-users. It is the central place to store various parameters used in an application.

 <h2>Application Deployment</h2>

 <p>

 Deploying a PRADO application mainly involves copying directories. For example, to deploy the above minimal application to another server, follow the following steps,

 <ol>

-<li>Copy the content under <code>wwwroot</code> to a Web-accessible directory on the new server.</li>

-<li>Modify the entry script file <code>index.php</code> so that it includes correctly the <code>prado.php</code> file.</li>

-<li>Remove all content under <code>assets</code> and <code>runtime</code> directories and make sure both directories are writable by the Web server process.</li>

 </ol>

 </p>

 

 <h2>Application Lifecycles</h2>

 <p>

-Like page lifecycles, an application also has lifecycles. Application modules can register for the lifecycle events. When the application reaches a particular lifecycle and raises the corresponding event, the registered module methods are invoked automatically. Modules included in the PRADO release, such as <code>TAuthManager</code>, are using this way to accomplish their goals.

 <h2>Component Properties</h2>

 <p>

-A component property can be viewed as a public variable describing a specific aspect of the component, such as the background color, the font size, etc. A property is defined by the existence of a getter and/or a setter method in the component class. For example, in <code>TControl</code>, we have

 <pre class="source">

@@ -17,18 +17,47 @@ class TControl extends TComponent {

 }

 </pre>

-This defines a property named <code>ID</code>. Reading the property (e.g. <code>echo $component-&gt;ID;</code>) is equivalent to invoking the getter method (e.g. <code>echo $component-&gt;getID();</code>); and writing the property (e.g. <code>$component-&gt;ID='Button';</code>) is equivalent to invoking the setter method (e.g. <code>$component-&gt;setID('Button');</code>).

+</p>

+<p>

+To get or set the <tt>ID</tt> property, do as follows, just like working with a variable,

+<pre class="source">

+$id = $component-&gt;ID;

+$component-&gt;ID = $id;

+</pre>

+This is equivalent to the following,

+<pre class="source">

+$id = $component-&gt;getID();

+$component-&gt;setID( $id );

+</pre>

 </p>

 <p>

 A property is read-only if it has a getter method but no setter method. Since PHP method names are case-insensitive, property names are also case-insensitive. A component class inherits all its ancestor classes' properties.

 </p>

 

+<h3>Subproperties</h3>

+<p>

+A subproperty is a property of some object-typed property. For example, <tt>TWebControl</tt> has a <tt>Font</tt> property which is of <tt>TFont</tt> type. Then the <tt>Name</tt> property of <tt>Font</tt> is referred to as a subproperty (with respect to <tt>TWebControl</tt>).

+</p>

+<p>

+To get or set the <tt>Name</tt> subproperty, use the following method,

+<pre class="source">

+$name = $component-&gt;getSubProperty('Font.Name');

+$component-&gt;setSubProperty('Font.Name', $name);

+</pre>

+This is equivalent to the following,

+<pre class="source">

+$name = $component-&gt;getFont()-&gt;getName();

+$component-&gt;getFont()-&gt;setName( $name );

+</pre>

+

+</p>

+

 <h2>Component Events</h2>

 <p>

 Component events are special properties that take method names as their values. Attaching (setting) a method to an event will hook up the method to the places at which the event is raised. Therefore, the behavior of a component can be modified in a way that may not be foreseen during the development of the component.

+</p>

+

+<h2>Namespaces</h2>

+<p>

+A namespace refers to a logical grouping of some class names so that they can be differentiated from other class names even if their names are the same. Since PHP does not support namespace intrinsically, you cannot create instances of two classes who have the same name but with different definitions. To differentiate from user defined classes, all PRADO classes are prefixed with a letter 'T' (meaning 'Type'). Users are advised not to name their classes like this. Instead, they may prefix their class names with any other letter(s).

+</p>

+<p>

+A namespace in PRADO is considered as a directory containing one or several class files. A class may be specified without ambiguity using such a namespace followed by the class name. Each namespace in PRADO is specified in the following format,

+<pre class="source">

+PathAlias.Dir1.Dir2

+</pre>

+where <tt>PathAlias</tt> is an alias of some directory, while <tt>Dir1</tt> and <tt>Dir2</tt> are subdirectories under that directory. A class named <tt>MyClass</tt> defined under <tt>Dir2</tt> may now be fully qualified as <tt>PathAlias.Dir1.Dir2.MyClass</tt>.

+</p>

+<p>

+To use a namespace in code, do as follows,

+<pre class="source">

+Prado::using('PathAlias.Dir1.Dir2.*');

+</pre>

+which appends the directory referred to by <tt>PathAlias.Dir1.Dir2</tt> into PHP include path so that classes defined under that directory may be instantiated without the namespace prefix. You may also include an individual class definition by

+<pre class="source">

+Prado::using('PathAlias.Dir1.Dir2.MyClass');

+</pre>

+which will include the class file if <tt>MyClass</tt> is not defined.

-A service is uniquely identified by its <code>ID</code> property. By default when <code>THttpRequest</code> is used as the <a href="?page=Fundamentals.Modules#request">request module</a>, GET variable names are used to identify which service a user is requesting. If a GET variable name is equal to some service <code>ID</code>, the request is considered for that service, and the value of the GET variable is passed as the service parameter. For page service, the name of the GET variable must be <code>page</code>. For example, the following URL requests for the <code>Fundamentals.Services</code> page,

-PRADO implements <code>TPageService</code> to process users' page requests. Pages are stored under a directory specified by the <code>BasePath</code> property of the page service. The property defaults to <code>pages</code> directory under the application base path. You may change this default by configuring the service in the application configuration.

-Pages may be organized into subdirectories under the <code>BasePath</code>. In each directory, there may be a page configuration file named <code>config.xml</code>, which contains configurations effective only when a page under that directory or a sub-directory is requested. For more details, see the <a href="?page=Configurations.PageConfig">page configuration</a> section.

-Service parameter for the page service refers to the page being requested. A parameter like <code>Fundamentals.Services</code> refers to the <code>Services</code> page under the <code>&lt;BasePath&gt;/Fundamentals</code> directory. If such a parameter is absent in a request, a default page named <code>Home</code> is assumed. Using <code>THttpRequest</code> as the request module (default), the following URLs will request for <code>Home</code>, <code>About</code> and <code>Register</code> pages, respectively,
