如何直接从出勤记录

Question

MySQL数据库表：（名称：出席）

RecID | EmployeeID | Date     | Name | WorkedHours | Absence | OverTime
------+------------+----------+------+-------------+---------+---------
434   | 7          | 19/11/16 | Jack | 8           |         | 1
435   | 7          | 20/11/16 | Jack | 8           |         | 0
436   | 7          | 21/11/16 | Jack | 8           |         | 0
437   | 8          | 19/11/16 | Nik  | 8           |         | 1
438   | 8          | 20/11/16 | Nik  | 0           |    1    | 0
439   | 8          | 21/11/16 | Nik  | 8           |         | 1

我想使用PHP显示以下工资报告：

 EmployeeID | Month | Name | WorkedDays| Deductions| Overtime | Net Pay
 -----------+-------+------+-----------+-----------+----------+--------
 7          | 11/16 | Jack | 3         |           |          | 1
 8          | 11/16 | Nik  | 2         |           |          | 0

到目前为止，我使用 SQL ：

进行了以下尝试

SELECT EmployeeID, Name, 
        COUNT(*) AS WorkedDays, 
        (COUNT(*) * $DailyWage) AS 'Net Pay'
        FROM `Attendance` 
        GROUP BY EmployeeID;

有没有办法通过 PHP 循环实现这一目标？像

这样的东西

$SQL = mysql_query("SELECT * FROM Attendance GROUP BY EmployeeID");
while($Row = mysql_fetch_array($SQL)){
        $WorkedDays++;
        echo "WorkedDays: " . $WorkedDays;
        // Doesn't make sense but just giving example.
    }

如果您需要任何细节，请告诉我。谢谢。
