Flex return value form php script

Question

if I have a php webservice function like this
public function loginCheck($myusername, $mypassword) {
    return $rec_count;
and and Declartion like this
    <accountloginservice:AccountloginService id="accountloginService"
                                             fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)"
                                             showBusyCursor="true"
    <s:CallResponder id="loginCheckResult" />
and a button
    <s:Button id="loginButton" label="Log In" click="loginButton_clickHandler(event)"/>
and a function trigger by a button like this
protected function loginButton_clickHandler(event:MouseEvent):void {
            loginCheckResult.token = accountloginService.loginCheck(usernameLogin.text,passworkLogin.text) ;
            var check:int = parseInt(loginCheckResult.lastResult);
            if (check == 1){
why the check variable always is NULL, and how to get the value of the php script???

Answer 1

Please post your code for your dataGrid and your PHP or a
sample of the returned XML. Without code, it is hard to say where
the problem is, but it seems like the issue is in your
[httpService].lastResult.[blah].[blah] syntax. It helps to set a
result event for PHP calls that you then bind to your dataGrid
rather than using the lastResult method which is hard to debug:
private function phpResult(evt:ResultEvent):void {
myDataGrid.dataProvider = evt.result;
But post your code and I'm sure we can figure out the
problem.
