问题
I've googled alot for this but unfortunately I found nothing close to what I'm looking for.
My idea is to have a plain PHP standalone client to send an Excel 2003 file (binary) to a controller of my CakePHP project. This is what i need to figure out how it is theoretically working.
Any helpful idea would be greatly appreciated.
Kind regards, Marius
