I am new in coding and sufferin from some basic issues. I searched for a topic to find the answer that I need but I could not find. I’ve been trying to write and searching codes for writting into xls file for 3 days but could not find a suitable one. The problem is:

I created a page with textareas and submit/reset button like that and I’ve got an excel table in document classgrades.xls. The colums of that table are named Name, Midterm1, Midterm2, Final, Attendance and Average.
Now, I am trying to write a code which automatically adds a new row and writes user inputs from textares into the excel table. If you help I appreciate very much and if you write the code briefly I can understand better.
The class I use to modify Excel documents is PHPExcel. Was at http://phpexcel.codeplex.com/ but I just googled and it’s moved to GitHib https://github.com/PHPOffice/PHPExcel.
Small warning: I have found it occasionnally buggy (turn off “NOTICE” and “WARNING” errors before diving in, for example – or at least you did when I last used it) but otherwise it’s easy to use.
It has some nice classes to navigate the workbooks and add rows. No point quoting examples here as there are lots of examples in the “test” section. https://github.com/PHPOffice/PHPExcel/tree/develop/Tests Use those and piece together what you need.
