发送PHP json_encode数组到jQuery不起作用

So I want to send a PHP array to jQuery but it's not working and I don't know why. Can someone help me out?

Here is the PHP:

$var1 = "hello";
$var2 = "world";
$values = array('value1'=>$var1,'value2'=>$var2);
echo (json_encode($values));

And the jQuery:

$.get("test.php", function(values){
var jsonValues = $.parseJSON(values);
$("showValue1").html(jsonValues.value1);
});

    I figured it out on my own! It's probably not the best way (I am just a beginner in this stuff) but it works.

    So I was trying to put the data from my database into an array. The code in my original post was just a sample version because I wanted to try the code first.

    This is what I came up with. The PHP:

    $array = array();
    
    while($row = mysql_fetch_assoc($rs)){     //$rs is mySQL query
        $array[] = $row;
    }
    
    echo $array[0]['post']. '&';       //post is the column name from my database
    echo $array[1]['post']. '&';
    echo $array[2]['post'];
    

    With Ajax I did this (thanks to stefanz!):

     $.ajax({
        method:    'GET',
        url:       'test.php',
        cache:     false,
        success:   function(data){
           var tmp = data.split("&");
           $('#showValue1').html(tmp[0]);
           $('#showValue2').html(tmp[1]);
           $('#showValue3').html(tmp[2]);
        }
    });
    

    Thanks everybody for helping me out! It lead me to the code I am using now.
