In addition to the lack of ncurses_wborder() documentation.
There is also the lack of the getyx function..
it is different than the getxy function I wrote (and posted to the main ncurses docs page on php.net) to get the max X and max Y values, instead it gives you your current Y and X values.
ncurses_getyx($z, $y, $x);// where $z = a window handle...
# the $y and $x are handed back as globals.
# so beware of using this in a function where you might be
# looping through any variable using those.
# do a 'man getyx' to see.
