you can use a datagrid if you want, or a tile list, or a list, or an advanced datagrid, it's entirely up to you and what you plan to do with the data.
The Full working basic code for what you're trying to do is this:
Flex code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="send_data()">
    <mx:Script>
    <![CDATA[
        import mx.rpc.events.ResultEvent;
        import mx.controls.DataGrid
        private function send_data():void
            userRequest.send();
        private function handleResult(evt:ResultEvent):void
            dg1.dataProvider = evt.result.player;
    ]]>
    </mx:Script>
    <mx:Label x="79" y="89" text="username"/>
    <mx:Label x="79" y="128" text="rolnumber"/>
    <mx:TextInput id="nm" x="153" y="87"/>
    <mx:TextInput x="153" y="126" id="roll"/>
    <mx:Button x="127" y="191" label="submit" id="sub" click="send_data()"/>
    <mx:HTTPService id="userRequest" result="handleResult(event)" url="http://localhost/connect.php" useProxy="false" method="POST">
        <mx:request xmlns="">
            <username>{nm.text}</username><rollnumber>{roll.text}</rollnumber>
        </mx:request>
    </mx:HTTPService>
    <mx:DataGrid id="dg1" x="69" y="261">
        <mx:columns>
            <mx:DataGridColumn headerText="Name" dataField="name"/>
            <mx:DataGridColumn headerText="Roll" dataField="roll"/>
        </mx:columns>
    </mx:DataGrid>
</mx:Application>
PHP Code:
<?php
    mysql_connect("localhost", "root", "") or die("cannot connect");
    mysql_select_db("std_db") or die("cannot select database");
    if ($_POST["username"])
        $name = mysql_real_escape_string($_POST["username"]);
        $roll = mysql_real_escape_string($_POST["rollnumber"]);
        $query = "INSERT INTO student (name , roll) VALUES ('$name', '$roll')";
        if(mysql_query($query))
            echo "sucessfully inserted";
        else
            echo" error occured";
    $query="SELECT * FROM student";
    $result = mysql_query($query);
    $num_rows = mysql_numrows($result);
    $i=0;
    while ($i < $num_rows)
        $getName = mysql_result($result,$i,"name");
        $getRoll = mysql_result($result,$i,"roll");
        print "<player><name>".$getName."</name><roll>".$getRoll."</roll></player>";
        $i++;
?>
