Why can't I put my code in a function?

Salutations VMware Community,

I have been playing with the vCloud Director v 1.0.2 PHP SDK for roughly the past couple of weeks and I am learning new things all the time but something that I cannot explain nor do I understand is I have a block of code running great, doing exactly what I expect and then I put it into a function, or try to, and it breaks...and I get variations of these messages :

I'm guessing that it has something to do with the HTTP2 package and I've seen a video that showed someone setting up their dev enviroment having to download and put some files from HTTP2 somewhere but I was able to get everything set up using pear install and apt-get.  If anyone is familar with what's going on and would shed some light on my situation I would greatly appreciate it.

thanks,

Jason.
