Question

我是网络编程的新手，我有跟踪开支的个人项目。直截了当，我有数据库数据包含本月和上个月的总支出。我可以手动显示它（通过回声）。但我无法将价值传递给高级系列。由于许多小的单独数据，我想使用php / mysql而不是json手动填充它。

Graph2.php

<?php
$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "mypassword";
$mysql_database = "mytraining";
$bd = mysqli_connect($mysql_hostname, $mysql_user, $mysql_password, $mysql_database);
if (mysqli_connect_errno()) {
        printf("Connect failed: %s\n", mysqli_connect_error());
        exit();
    }

$query2 = "select year(date) as y, month(date) as m, sum(amount) as p from expenditure_bak group by year(date), month(date) order by m ASC";  
$sth = mysqli_query($bd, $query2);
$rows = array();
$rows['name'] = 'Revenue';
while($r = mysqli_fetch_array($sth)) {
    $rows['data'][]= round($r['p'],2);
}
//echo join($rows['data'], ','); //able to display correct value 660.2,60

?>

那么，在highcharts系列中将数据：[] 放入正确的代码是什么。

输出应该像JSFiddle，但显然使用来自数据库的动态数据。

最后，我想展示类似的东西 Expenditure Tracking

Answer 1

您可能需要对数据进行编码。我建议你看一下Pass a PHP array to a JavaScript function的答案。基于此，您应该能够做到这样的事情：

JSON.parse(<?php echo json_encode(join($rows[data], ',')) ?>);

那么你应该能够得到你想要的结果。您可能不需要JSON.parse。

使用MySQL填充highcharts数据
