我想使用带有JSON的谷歌图表。
这是从我的php数据库生成我的JSON文件的文件：
<?php
//open connection to mysql db
$connection = mysqli_connect("localhost","root","root","register") or die("Error " . mysqli_error($connection));
//fetch table rows from mysql db
$sql = "SELECT * FROM tbl_users";
$result = mysqli_query($connection, $sql) or die("Error in Selecting " . mysqli_error($connection));
//create an array
$emparray = array();
while($row =mysqli_fetch_assoc($result))
{
$emparray[] = $row;
}
header('Content-Type: application/json');
//write to json file
$fp = fopen('users.json', 'w');
fwrite($fp, json_encode($emparray));
fclose($fp);
//close the db connection
mysqli_close($connection);
?>
我的JSON OUTPUT是：

但谷歌这样说：
表没有列
这是我用来显示图表的方法：
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
function drawChart() {
var jsonData = $.ajax({
url: "getData.php",
dataType:"json",
async: false
}).responseText;
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(jsonData);
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
chart.draw(data, {width: 800, height: 400});
}
</script>
<div id="chart_div"></div>
我做错了什么？
