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.

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();

?>
