PHP data into Existing Excel Spreadsheet

I have a php system which has a MySql database which I can access in many number of ways. I have an existing spreadsheet with multiple worksheets in it. I need data streamed into the First Worksheet only but need to keep the integrity of the additional worksheets. I dont' need formatting and don't require anything else but the data to be streamed into certain cells on the first worksheet and keep all the additional worksheets intact.
