Flex以PHP输入和输出(Flex input and output in PHP)

 我想在flex中将输入值打印到PHP。 
 
 我的Flex代码... 
 
<mx:HTTPService id="sendReq" result="google(event)" showBusyCursor="true" method="POST" url="http://localhost/search/index.php" useProxy="false">
        <mx:request xmlns="">
            <keyword>
                {keyword.text}
            </keyword>
        </mx:request>
    </mx:HTTPService>

    <mx:TextInput text="" id="keyword" left="130.5" top="89" right="228.5" height="40" fontSize="20" fontWeight="bold" borderStyle="outset" focusThickness="0"/>

    <mx:Button click="sendReq.send();" id="search" label="search"  right="133.5" top="91" height="40" width="75" alpha="1.0" fillAlphas="[1.0, 1.0]"/>
 
 我的PHP代码， 
 
$keyword = $_POST['keyword'];
echo $keyword;
 
 但我无法从Flex接收关键字。 任何人都可以在这里找到我无法得到的错误。 

I want to print the input value in flex to PHP. 
 
My Flex Code... 
 
<mx:HTTPService id="sendReq" result="google(event)" showBusyCursor="true" method="POST" url="http://localhost/search/index.php" useProxy="false">
        <mx:request xmlns="">
            <keyword>
                {keyword.text}
            </keyword>
        </mx:request>
    </mx:HTTPService>

    <mx:TextInput text="" id="keyword" left="130.5" top="89" right="228.5" height="40" fontSize="20" fontWeight="bold" borderStyle="outset" focusThickness="0"/>

    <mx:Button click="sendReq.send();" id="search" label="search"  right="133.5" top="91" height="40" width="75" alpha="1.0" fillAlphas="[1.0, 1.0]"/>
 
My PHP code, 
 
$keyword = $_POST['keyword'];
echo $keyword;
 
But i am not able to receive the keyword from Flex. Can anyone find the error down here which i am not able to get.
