SQL to HTML Table, new-CodePudding

I can't figure out why my code isn't working? When i run it the page is blank!

This is a Harry Potter Database. I am trying to put the data within my SQL Database in a HTML Table. Sounds easy but I can't figure out why my code is not working!

<!DOCTYPE html>
<html>
<head>
    <title> Harry Potter Database </table>
</head>
<body>
<table>
    <tr>
        <th> ID </th>
        <th> Name </th>
        <th> Age </th>
        <th> Website </th>
    </tr>
<?php
ini_set('display_errors', 1); 
ini_set('display_startup_errors', 1); error_reporting(E_ALL); 
$conn = mysqli_connect("localhost", "root", "", "survey");
$sql = "SELECT * FROM result";
$res = $conn->query($sql);

if($res->num_rows > 0)
{
    while($row = $res->fetch_assoc())
    {
        echo "<tr>
        <td>". $row["ID"] . "</td>
        <td>". $row["Name"] . "</td>
        <td>". $row["Age"] . "</td>
        <td>". $row["Website"] . "</td>
        </tr>";
    }
}
else{
    echo "No RESULTS";
}
$conn->close();

?>
</table>
</body>
</html>

result is the name data within my database called survey

Undefined array key "ID" in C:\xampp\htdocs\ws5\sqlquery.php on line 26

This is the error in the source

Structure of Table

ID	WEBSITE	AGE	WEBSITE

CodePudding user response：

On Windows (where it looks like you are), MySQL stores all table and column names in lowercase by default (see the docs for "Identifier Case Sensitivity" and lower_case_table_names).

That means that instead of "ID", you should be using "id", instead of "Name" it should be "name", etc.
