推荐答案

计算百分比的算法就像这个，

The algorithm to calculate the percentage would be like this one,

(obtained marks / total marks) * 100

。在你的情况下，获得的标记将来自7个文本框的值的总和，总标记将更像700或取决于课程。乘以100得到百分比。您可以在PHP中编写整个过程来捕获所有textBox的值，并将它们添加到变量中。然后运行上面的表达式，它将解析为包含百分比的值。

.. in your case, obtained marks will come from the sum of the 7 textBoxes' values, and the total marks would be more like 700 or depends on the courses. Multiply by 100 to get the percentage. You can write the whole process in PHP to capture the values for all of the textBoxes, and add them up in a variable. Then run the above expression, it will resolve to a value that will contain the percentage.
