ncurses_flushinp
While function ncurses_nodelay() is still not implemented and if you need a non-blocking getch,
following code might help.
<?php
$init = ncurses_init();
$full = ncurses_newwin (0,0,0,0);
ncurses_wborder($full,0,0,0,0,0,0,0,0);
ncurses_wrefresh($full);
$running = true;
$fp = fopen("php://stdin","r"); //open direct input stream for reading
stream_set_blocking($fp,0); //set non-blocking mode
while ($running) {
while (($buf = fgets($fp, 4096)) != false) { //fgets is required if we want to handle escape sequenced keys
$buffer .= $buf;
}
if ($buffer != "") {
switch ($buffer) {
case " ": { //exit on space key
ncurses_end();
exit;
}
default: {
ncurses_mvwaddstr($full,2,2,"$buffer"); //display input
}
}
$buffer = ""; //empty buffer
}
// You can do something interesting here, while we're not waiting for an input
ncurses_mvwaddstr($full,4,4,microtime(true));
ncurses_wrefresh($full);
usleep(1); //reduce cpu usage
}
?>

After banging my head over this for awhile, I discovered, you must use ncurses_keypad($window, true); to enable the arrow keys and f keys to work correctly.

When using getch to capture KEY_* events remember that the keypad is arranged like this:
+-----+------+-------+
| A1 | up | A3 |
+-----+------+-------+
|left | B2 | right |
+-----+------+-------+
| C1 | down | C3 |
+-----+------+-------+
You use has_key to capture these and act upon them.
man curs_getch for more info.
