执行此操作的方法有很多，区别在于您希望存储的深度.在不浪费太多时间的情况下，以下是存储选项的快速列表:

There are many ways to do this, the differences come down to how 'deep' you want the storage to be. Without wasting too much time here is a quick list of storage options:

• POST vars(这是最适合您的情况的解决方案)

• 会话
• 数据库

基本上，最简单的技术是获取传递的数据并重新显示，因此对于您的表单，您有2个输入， leftval & rightval ，用户点击表单上的Submit，然后将它们相乘以显示结果.

Basically the simplest technique is to take the data that is passed and redisplay it, so for your form you have 2 inputs, leftval & rightval, the user hits submit on the form and you multiply them to show the result.

构建页面以显示结果时，请使用$ _POST ['leftval']&$ _POST ['rigtval']将其填充到新页面上.确保对这些值进行清理，并在退出过程中将其转义！

When you build the page to show the result use the $_POST['leftval'] & $_POST['rigtval'] to populate them on the new page. Make sure to sanitize the values and escape them on the way out!
