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...

+--------------------------------------+

|+---+                                  |

||   |                                  | 

|+---+                                 | 

|                                        |

|+------------------------------------+|

||                                      ||
