90637 PHP Script to edit Excel file

Need simple PHP script to edit Excel spreadsheet fields. Script will replace various cells inside the Excel file with new values (can be numbers and/or formulas) Script will ask what cells (A2, C6 ..etc) need to be updated, then will ask for what to update those cells with. The user will then enter the data for those fields. Then the script will update the Excel file and save it. The Excel file and php script will reside on the same computer, so the script will be writing to local file. If interested in this please respond and tell me about what similiar works you have done regarding Excel and php. Since this is a relatively simple task using OLE automation or other methods .. I'd like this script ASAP so we can discuss the next project which will be adding to this script. Please respond if you are ready to start now, and can finish as soon as today. thanks
