ncurses uses color pairs to specify both foreground and background colors. Use ncurses_init_pair() to define a color pair.
Parameters

The color pair from which to get the foreground and background colors to set as the active colors.

<?php
ncurses_init();
// If the terminal supports colors, initialize and set active color
if (ncurses_has_colors()) {
ncurses_start_color();
ncurses_init_pair(1, NCURSES_COLOR_YELLOW, NCURSES_COLOR_BLUE);
ncurses_color_set(1);
}
// Write a string at specified location
ncurses_mvaddstr(10, 10, "Hello world! Yellow on blue text!");
