Ajax PHP Jquery - echo-ing back data

I'm having trouble bringing back data from my PHP file. I guess I don't really understand the data parameter of this jquery function so I just went off some tutorials.

Jquery

$.ajax(

    {

        url: 'test.php',

        dataType: 'text',

        data: {test: '1'},

        success: function(data)

        {

            window.alert(data);

        }

    })

Now from my understanding the test: declares the variable used in php and 1 is the value in that variable. But I'm not entirely sure...

Here's my PHP

$item1 = $_POST['test'];



    echo $item1;

Now it's just supposed to alert that value so I know it is at least returning something but in the alert it's just blank so I'm losing the value somewhere, but where?

use $_REQUEST it will handle both the GET and POST

$item1 = $_REQUEST['test'];

by default ajax request is GET type, either specify expilicitly the type like

$.ajax(

    {

        url: 'test.php',

        type:'POST'

        dataType: 'text',

        data: {test: '1'},

        success: function(data)

        {

            window.alert(data);

        }

    })

or use $_GET like

item1 = $_GET['test'];



    echo $item1;
