Posting to Steem with Plain PHP

[BlockChainBobC]

Hey is it possible to create a post (broadcast comment) with this library? I know using curl you can send JSON requests directly to https:/api.steem.com and get some data back. But I can not seem to figure out how to post content using just php... There is a project called graphene node that requires some custom dependencies be installed via ssh on the server level, but I am trying to get something working that will operate on plain vanilla shared web hosting like blue host or hostgator....

Let me know if this lib can help me or if there is a way to extend it so it could!
