Questions about how to dynamically insert values of multiple rows-php Tutorial

The problem of the value of dynamic insertion of plural rows is now a problem. PHP and SQLServer2008 are used as a logon system. After you press the "line" button, two rows are automatically appended, and two rows are in the same group. (1--2 is the first group, and 2--2 is the second group.) press the "login" button to input everything entered by the client to the DB. However, the value of that Table is dynamically inserted and does not take the value. Others say that the value of dynamically creating trtd and inpu in js is a problem of dynamically inserting the plural rows.
Problems that are currently plagued. PHP and SQL Server are used as a logon system.

However, the value of that Table is dynamically inserted and does not take the value.


Others say that js is used to dynamically create tr td and input, and php can directly Traverse

$ _ GET or $ _ POST, the array can GET all values ..


To sum up, from the perspective of this system, we mainly want to retrieve the input value from every two groups of rows in the dynamic Table and then bring it into the DB.
