While function ncurses_nodelay() is still not implemented and if you need a non-blocking getch,
following code might help.
$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
}

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.

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.

A custom php ncurses_getstr function..
<?php
function ncurses_getstr($strlen){
for ($x=0;$x<$strlen;$x++){
$string .= chr(ncurses_getch());
}
return $string;
}
ncurses_init();
ncurses_addstr(ncurses_getstr(6));
ncurses_refresh();
ncurses_getch();
ncurses_end();
?>
