使用PHP从多个MySQL表填充HTML表

我现在正在从头开始学习PHP，以便从头开始组建薪资系统。

我正在尝试编写PHP代码以从用户和项目数据库中抽出数小时，并按照日期和项目细分为每个用户安排整齐的时间表。

目前，我在给定特定用户和日期范围的情况下从数据库中提取所有记录，然后使用while循环显示数字。它每个项目每天不能处理多个时间表，或者在给定的一天中有0小时。

我正在使用的代码很长很乱，看起来像这样：

        <?php
        mysql_connect("localhost","root","");
        mysql_select_db("gemsclip");

        // Check connection
        if (mysqli_connect_errno()){
            echo "Failed to connect to MySQL: " . mysqli_connect_error();
        }
        $date_range_start = "2014-02-02";
        $date_range_end = "2014-02-08";

        $query = ("SELECT 
                    a.user_id, 
                    a.first_name, 
                    a.last_name, 
                    a.department, 
                    a.supervisor, 
                    b.date, 
                    b.clock_in, 
                    b.clock_out, 
                    b.project, 
                    b.project_id, 
                    b.time_diff
                    FROM user a, date b
                    WHERE a.user_id = b.user_id and a.user_id = ".$_SESSION['user_id']." and b.date >= '$date_range_start' and b.date <= '$date_range_end'");

        $result = mysql_query($query);
        $hours = 0;

        while ($row = mysql_fetch_assoc($result)) {

            $project = $row['project']." (".$row['project_id'].")";
            $time_diff = $row['time_diff'];
            $user = $row['user_id'];
            $date = $row['date'];
            $time = [];

            $last_name = $row['last_name'];
            $first_name = $row['first_name'];
            $department = $row['department'];
            $supervisor = $row['supervisor'];
        }

是否有更高效/更简单的方法将数据从SQL加载到这样的表中？当我需要稍后使用PHPExcel将其转换为excel时，我是否会遇到以这种方式格式化数据的问题？
