Something worth noting here; I noticed that with ncurses_wgetch function keys are broken into multiple codes while ncurses_getch returns only one attributed code. 



For example, with ncurses_wgetch pressing an up arrow results in three codes 27 91 65 (an ascii escape sequence). The problem is subsequent calls to ncurses_wgetch are required to acquire all three codes. Unfortunately, pressing an "A" key for example would result in only a single code of 65. This makes it hard to trap for both function keys and regular keys.



However, with ncurses_getch an up arrow results in a single attributed code of 259 or the "NCURSES_KEY_UP" key constant. An "A" key is still 65.

By default ncurses_wgetch does not return keypad keys.  If you need to use function or arrow keys in a sub window, simply do this first.



ncurses_keypad($win, TRUE);

Heres a function to get a string from a specific window and return it on ENTER.





// Dynamic String Input (converts INT ASCII to CHAR)


function ncurses_wgetstr($win){


    $strlen = 1;


    for ($sx=0;$sx<$strlen;$sx++){


        $strlen++;


        $ch = ncurses_wgetch($win);


        if ($ch == 13){


            return $str;


            break 2;


        }


        $str .= chr($ch);


    }


}





Example:





$ncurse = ncurses_init();


$fullscreen = ncurses_newwin (0,0,  0,0); 


ncurses_border(0,0,  0,0,  0,0,  0,0);


ncurses_refresh();





while (1){


    $keyPressed = ncurses_wgetstr($fullscreen);


    ncurses_wrefresh($fullscreen);


}
