通过AJAX通过PHP获取数据无法正常工作

I am having problems getting data from a server using a combination of generating the data through PHP and using an ajax method to retrieve it.

I want to get the data through GET within receive.php that calls get_data.php

My ajax function located within receive.php:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script type = "text/javascript">
    $.ajax({
       url: '<website>/get_data.php',
       data: {
          format: 'json'
       },
       error: function() {
          $('#info').html('<p>An error has occurred</p>');
       },
       dataType: 'jsonp',
       success: function(data) {

        console.log(data);

       },
       type: 'GET'
    });
</script>

get_data.php:

<?php
...
$data = array('a','b','c');
$data = json_encode($long);
echo $data;

?>

When I run receive.php I get an ajax error: GET 404 error.

What am I missing?
