Help me understand this!

Hi everyone. I'm having trouble understanding how this works:

My website generates a qr code after the customer purchases a product. The page displays the code & emails them the code via an attachment as a pdf image. However, in order to send the code as an attachment, it has to be saved locally first. This is where I am confused:

When the customer enters this page, and the qr code is generated & sent via email, does the script save the qr code in the web server space OR it in the customers directory?

The script should save the code in the web server right? Since all the scripts reside in the web server. However the customer is activating the page/script. I'm just confused as to where exactly the code is being saved, because I obviously can't save something with the customer.

Well, if that's how your script works, then yes; written differently it need not be.

Your script running on your computer has no way to save files on random computers of random people elsewhere in theworld.

because I obviously can't save something with the customer.

Well, you just answered your own question.
