Platform.api access for php scripts?

Is the platform.api available to php scripts (both custom scripting service and pre/post script processors)?

I’m using post-processor to send notification of updates to one of my mysql databases, and can grab the change via the $event object. However I would like to pull all the table records w/o having to log in with curl and get a session and do another curl call to get the record and then yet another cur. call to send my notification when all of these are available as services.

I can’t use v8js for several reasons, one being I am generating an XML record on the fly and doing that is JS is a bit of a goat rope.
