I was hoping someone could tell me how to run server side code to process a file?
Basically, I want users to upload a file to my site, and once the file is uploaded, I want server side code (I'm thinking PHP) to process the file. Also, I want this code to run even if the user naviagtes away from the page. Can anyone point me to some links that would show me how to do this?
Also, any links on working with .xls files in PHP would be greatly appreciated also.
Thanks for any help!
