如何专门从数据库调用表属性？

Question

我正在尝试在表testing_data中是否使用Camp数据。我在检索数据并在其他情况下调用它时是否正确做到了..我真的是php新手..希望您可以帮助我..tq

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "brindley";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 


$sql = "SELECT * FROM testing_data";
$result = $conn->query($sql);
$user = mysqli_fetch_array($result);


if($user["t_month"] === 'Q1')
{
    if($user['t_bbq'] === 'Kambing Golek')
    {
        if($user['t_participant'] =='>=21 to <=40')
        {
            if($user['t_outdoor'] == 'Tiada')
            {
                if($user['t_packages']== 'Pakej 4')
                {
                    echo "YES, People prefer choose packages like this";
                }
                else 
                {
                     echo "NO";
                }
            }
        }
}
?>
