Return Values
Returns 0 on success, or -1 if the color table could not be allocated or ncurses was not initialized.
Examples
Example #1 Writing a string with a specified color to the screen
<?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!");
// Flush output to screen
ncurses_refresh();
ncurses_end();
