asterisk users - Sep 2014 - read digits from the user through php agi script

hi everyone,
actually i want to release an IVR system using PHPAGI API , in this IVR i
want to get value from the user.
I already used get_data defined in phpagi but they are not able to get the
value given by the user and store it in a php variable.
i tested this :
$result = $agi->get_data('beep', 3000, 20);
$keys = $result['result'];

but every time i found in $keys variable 0.

please any help or suggestions
thank you for spending your valuable time for me.

I?m not going to help you debug your code, but I wanted to post part of a
function from one of our internal AGIs which reads auth codes using a simple
IVR.  The code is ugly but it might be helpful to you.   This code is released
to the public domain.

    // no pin provided, get pin from caller
    $agi->answer();
    usleep(250000);

    $try = 1;
    $bad_pass = FALSE;
    $auth_start_time = microtime(TRUE);
    while ($try < 4) {
        if ($try == 1) {
            $agi->exec("Read",
"pin,/igc/sounds/cc-bong,$pinset_len,,1,3");
        } else {
            if ($pinset_len == 0) {
                $agi->exec("Read",
"pin,please-enter-your&access-code&/igc/sounds/cc-bong,,,1,5");
            } else {
                $agi->exec("Read",
"pin,please-enter-your&digits/$pinset_len&digit&access-code&/igc/sounds/cc-bong,$pinset_len,,1,5");
            }
        }
        $temp = $agi->get_variable("pin");
        $pin = trim($temp["data"]);

        if ($pinset_verify == "1" && $pin != "") {
            $temp = array_search($pin, $pins);
            if ($temp !== FALSE) {
                $agi->set_variable("SM_START", $sm_start +
(microtime(TRUE) - $auth_start_time));
                $agi->exec("CELGenUserEvent",
"\"SM,status => OK, cause =>000, detail => Verified PIN, pin
=> $pin\"");
                return array("status" => "OK",
"cause" =>"000", "detail" => "Verified
PIN", "pin" => $pin);
            }
        } else if ($pinset_verify != "1" && $pin !=
"") {
            $agi->set_variable("SM_START", $sm_start +
(microtime(TRUE) - $auth_start_time));
            $agi->exec("CELGenUserEvent", "\"SM,status
=> OK, cause =>000, detail => Unverified PIN, pin =>
$pin\"");
            return array("status" => "OK",
"cause" =>"000", "detail" =>
"Unverified PIN", "pin" => $pin);
        }

        if ($try != "1") {
            $agi->exec("Playback",
"bad&access-code");
        }
        $try++;
    }

    $agi->set_variable("SM_START", $sm_start + (microtime(TRUE) -
$auth_start_time));
    $agi->exec("CELGenUserEvent", "\"SM,status =>
ERROR, cause =>851, detail => Verified PIN, pin => $pin\"");
    return array("status" => "ERROR", "cause"
=>"851", "detail" => "Verified PIN",
"pin" => $pin);

}

Why do you want to do this in an AGI?  It's easy enough to do in the
dialplan.
Here's how I did it; you'll need to substitute your own sound bytes, 
obviously, but I've added comments showing what they say:


[get_pin]
exten => s,1,Set(pin=)
exten => s,n,Set(PINLENGTH=4)
;  "Enter your PIN. If you make a mistake, press STAR."
exten => s,n(prompt),Background(ajs-enter_pin)
;  Build up the PIN digit by digit.  The WaitExten() will be cut short by any
;  keystroke, so we can use a quite longish timeout.
exten => s,n(nextdigit),WaitExten(30)
;  "Sorry, I didn't get that."
exten => s,n,Playback(ajs-sorry_didnt_get)
exten => s,n,GoToIf($[${LEN(${pin})}<1]?prompt:saysofar)
;  "The digits entered so far are:"
exten => s,n(saysofar),Playback(ajs-digits_so_far)
exten => s,n,SayDigits(${pin})
exten => s,n,Goto(nextdigit)

;  This context needs to have a "h" extension; because we may well be
;  placing a call from here, if the PIN was correct.

exten => h,1,NoOp(Clearing up)
;  .....  carry on tidying up after ourselves

;  "PIN cleared.  Start again from the beginning."
exten => *,1,Playback(ajs-start_again)
exten => *,2,GoTo(get_pin,s,1)

exten => #,1,Hangup()

exten => _X,1,Set(pin=${pin}${EXTEN:0:1})
exten => _X,n,NoOp(PIN so far is ${pin})
exten => _X,n,GoToIf($[${LEN(${pin})}>=${PINLENGTH}]?got_all:need_more)
exten => _X,n(need_more),GoTo(get_pin,s,nextdigit)
;  We have all 4 digits .....
exten => _X,n(got_all),NoOp(PIN is ${pin})
;  .....  and we continue from here with the PIN in ${pin}
