MySQL在3DArray PHP中的结果

// 连接MySQL数据库
$servername = "数据库服务器地址";
$username = "用户名";
$password = "密码";
$dbname = "数据库名";

$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 执行MySQL查询
$sql = "SELECT * FROM 表名";
$result = $conn->query($sql);

// 将查询结果存储在3D数组中
$threeDArray = array();

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        $threeDArray[$row['维度1']][$row['维度2']][$row['维度3']] = $row;
    }
} else {
    echo "没有结果";
}

// 关闭数据库连接
$conn->close();

// 打印3D数组
print_r($threeDArray);
