如何在 Javascript 中访问 PHP 变量？

Question

I'm making a pie chart of expenses using JavaScript and CodeIgniter.我正在使用 JavaScript 和 CodeIgniter 制作费用饼图。

Controller控制器

chart_c
function getchart1() {
    $result['query']=$this->model_m->getchart2();
    $this->load->view('chartview',$result);
}
model_m
function getchart2() {
    $query = $this->db->get('qpaper');
    return $query->result();
}

View看法

foreach($query as $row) {
    $ex=$row->expenses;
    $cat=$row->category;
}

How can I access $row->expenses and $row->category from the script above in the following JavaScript?如何在以下 JavaScript 中从上面的脚本访问$row->expenses和$row->category ？

var data = google.visualization.arrayToDataTable([
    ['Task', 'Hours per Day'],////how i will insert the data from db 
    ['Work',     11],///my doubt here $e how i will put here
    ['Eat',      2],
    ['Commute',  2],
    ['Watch TV', 2],
    ['Sleep',    7]
]);

If its just you want a pie chart using php array, you could use Highcharts .如果它只是你想要一个使用 php 数组的饼图，你可以使用Highcharts 。 Check their Edit in Jsfiddle page.检查他们在 Jsfiddle 页面中的编辑。 You just need to pass data in json format to generate the chart.您只需要以json格式传递数据即可生成图表。 I think you already have php array, convert it into json format and pass it to this highchart function.我想你已经有了 php 数组，将其转换为 json 格式并将其传递给这个 highchart 函数。
