Webface is an underlying technology that abstracts the control and visual aspects of a web page, away from the control logic.

It comprises of four components:

• Web_View
• Web_Auth
• Web_Ctrl
• Web_Dbug

Covering them individually...

• Web_View
This covers all the visual aspects.
• htmlStart & htmlEnd
• borders
• splitting into panes
Important points:
• Everything uses strings, not print
• Default implementation based around tables, not CSS
• Web_Auth
Determines whether a user is carry out a particular task. Since these tasks are application-specific, most developers will create their own implementation of this class' single method:

    function isUserValidFor($purpose, $access = "w")

• Web_Ctrl
This builds control code to pass parameters between one invocation of the script, and the subsequent one.
The default uses the GET message.
• getParameterValue
• createAnchor
• createAnchorParam
A typical GET request might look like this:

http://www.warpdemo.homelinux.net/index.php?WRP001X1_current=0&
  WRP003X3_current=1&MIN004A4_current=0&WRP004X5_sort=11&WRP004X5_mx=10&
  WRP004X5_opt=&WRP005X6_sort=11&WRP005X6_mx=10&WRP005X6_opt=&
  wintype=main&content=WRP003X&max=WRP003X

WARP, makes this easier.
• Web_Dbug
Essential debug and tracing methods.
• Error, warning, and info levels
• Stores multiple errors
• Defaultly with output in HTML, but can be amended to trace to alert boxes, system logs files, etc, but overriding the methods.
• Web_Face
Everything comes together in this single interface object. Essentially, it's:

    function Web_Face()
    {
        $this->view = new Web_View;
        $this->ctrl = new Web_Ctrl;
        $this->auth = new Web_Auth;
        $this->dbug = new Web_DBug;
    }

If you simply pass a Web_Face reference around your code, and you can do anything!
