Keep in mind, you need to do a ncurses_refresh before any window drawing options to display the window correctly.

for example
ncurses_wclear($window);
ncurses_wborder($window, 0, 0, 0, 0, 0, 0, 0, 0);
ncurses_wrefresh($window);

won't work correctly the first time though the loop (not sure why),

but throw on a ncruses_refresh at the top and it displays correctly

Here is a functional example of drawing dynamic windows and refreshing them using ncurses_wrefresh.

This draws the main window, borders it, creates a small window borders it, creates a lower window and borders it as well. it also shows an example of doing a little backgrounding..

<?php
/*
the window will look somewhat like this...
+--------------------------------------+
|+---+                                  |
||   |                                  | 
|+---+                                 | 
|                                        |
|+------------------------------------+|
||                                      ||
|+------------------------------------+|
