求教一道关于jquery里$.post()函数与php数组之间数据传递的问题?
代码如下

A.html

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Insert title here</title>

<script type="text/javascript" src="jQuery.js"></script>

<script>

  $(function () {

  $.post("cx2.php", {name:'cx', number:'1'}, function(data){

  alert(data.a);

  }, "json");

  })

</script>

</head>

<body>

  <h2>hhhhh</h2>

</body>

</html>

——————————

cx2.php

<?php

  $name = $_POST['name'];

  $number = $_POST['number'];

  var arr = array('a'=>"tt", 'b'=>"tt2", 'c'=>"tt3");

  print_r(arr);

?>

运行后得不到php里的数组,求大侠讲解一下,最好贴出修改后的代码


------解决方案--------------------
cx2.php 下面这样写 
PHP code
$arr = array('a'=>"tt", 'b'=>"tt2", 'c'=>"tt3");
 echo json_encode($arr);
