Question

我最近开始从事Highchart的工作。我没有深刻的知识。但我仍然在尝试我的水平。我尝试了很少的代码，但我没有得到任何结果。浏览器控制台没有加载任何内容，它显示为空白。能帮我指点下一步做什么吗？我最好的尝试了我的水平。请我出去。

这是我的代码：

数据库编码：php.data

<?php
    //open connection to mysql db
    $connection = mysqli_connect("localhost","root","root","demo") or die("Error " . mysqli_error($connection));

    //fetch table rows from mysql db
    $sql = "select * from project_requests";
    $result = mysqli_query($connection, $sql) or die("Error in Selecting " . mysqli_error($connection));


    //close the db connection
    mysqli_close($connection);
?>

的index.php

<!DOCTYPE HTML>
<?php 

include_once 'data.php'; 


?>

我的sql：数据库快照
