+Sample: Hangman Game
+
+Having seen the simple "Hello World" application, we now build a more complex application called "Hangman Game". In this game, the player is asked to guess a word, a letter at a time. If he guesses a letter right, the letter will be shown in the word. The player can continue to guess as long as the number of his misses is within a prespecified bound. The player wins the game if he finds out the word within the miss bound, or he loses.
+
+
+To facilitate the building of this game, we show the state transition diagram of the gaming process in the following,

+
+To be continued...

+
+Sample: Hello World
+
+"Hello World" perhaps is the simplest interactive PRADO application that you can build. It displays to end-users a page with a submit button whose caption is Click Me. When the user clicks on the button, the button changes the caption to Hello World.
+
+
+There are many approaches that can achieve the above goal. One can submit the page to the server, examine the POST variable, and generate a new page with the button caption updated. Or one can simply use JavaScript to update the button caption upon its onclick event.
+
+
+PRADO promotes component-based and event-driven Web programming. The button is represented by a TButton object. It encapsulates the button caption as the Text property and associates the user button click action with a server-side Click event. Therefore, the "Hello World" task can be handled intuitively and easily. One simply needs to attach a function to the button's Click event. Within the function, the button's Text property is modified as "Hello World". The following diagram shows the above sequence,
+
+
+
+The code that a developer needs to write is merely the following event handler function, where $sender refers to the button object.
+
+
+public function buttonClicked($sender,$param)
+{
+ $sender->Text="Hello World";
+}

+PRADO is an event-driven and component-based framework
+for Web application development in PHP 5.
+
+Components following the PRADO protocol are highly
+configurable and reusable. Properties defining
+the basic features of a component can be configured
+in specifications, templates or code.
+New components can be developed by either inheriting
+an existing component class or composing several
+components together. The work of using a component
+amounts to placing the component tag on the page template,
+configuring component properties, and writing handler
+functions to respond to component events.
+
+PRADO shares many similarities with ASP.NET and other
+RAD tools for Windows GUI development, such as Borland Delphi.
+In particular, it supports event-driven programming,
+viewstate maintenance, javascript, template, form validations, etc.
