You can open /dev/tty on unix systems or \con in windows, with ob_implicit_flush(true) to write output unbuffered.  Works like a charm :-)

-------------------------------

#!/usr/local/bin/php -q
<?php

set_time_limit
(0);
@
ob_end_flush();
ob_implicit_flush(true);

class
prompt {
  var
$tty;

  function
prompt() {
    if (
substr(PHP_OS, 0, 3) == "WIN") {
     
$this->tty = fOpen("\con", "rb");
    } else {
      if (!(
$this->tty = fOpen("/dev/tty", "r"))) {
       
$this->tty = fOpen("php://stdin", "r");
      }
    }
  }

  function
get($string, $length = 1024) {
    echo
$string;
   
$result = trim(fGets($this->tty, $length));
    echo
"\n";
    return
$result;
  }
}

echo
"Enter something or 'exit' to quit\n";
do {
 
$cmdline = new prompt();
 
$buffer = $cmdline->get("Something: ");
  echo
"You said: $buffer\n";
} while (
$buffer !== "exit");
echo
"Goodbye\n";

?>
