Donating to php.net

Hello, I am currently trying to set up a small web hosting site specializing in php websites. I would like to offer a donation option, where a portion of any profits made (trust me, profits here would be minimal) could be donated to php.net. Is there any sort of donation fund/account that would allow this? I guess what I'm asking is: how would I go about donating money to the php cause? Thanks, Chris p.s. I apologize if this question has been answered elsewhere, but I cannot seem to find it.
