PHP Paypal, without account?

I have a client who needs a donation system done (doesn't care with what system, just needs it to work) and it needs to be in PHP. I know that one can use PayPal to do this. However, the first problem is I do not know (and doubt) if the client has a PayPal business account or not, is it a good idea to cr开发者_如何学Ceate one to test it? Now, I know this might be a RTM question, but, is it possible to not care about how much money has been donated and not use IPN? I need as low complexity as possible.

In order to setup and start integrating Paypal in your app/web site, you may create a paypal developer account: https://developer.paypal.com/

EDIT: as noted in the comments, it's https://www.x.com/index.jspa now

You then have a sandbox in which you may test all PayPal transactions.

It may take more than a minute to create an account, last time I used it, it was very slow.

Of course I'd first check with your client whether she already uses or really wants to use Paypal in the future.
