CI导出CSV数据格式问题

I'm learning PHP & CodeIgniter 3. In this project I need to export some data to a CSV file. I'm able to export the CSV file, however the data is displaying incorrectly in a couple columns. Example (5.32856E+11) where it should be (532856165001). I'm able to see the actual value if you double click the cell.

Is there anyway to force the data in a CSV to display the data correctly?

This is the microsoft excel formatting and does not have any relation with your code just try to regenerate your csv and then re-open your file with a simple text editor (notepad++ or sublim text)
