I hope this isnt a to lowlevel question, but i got quite some problems getting started with the Twitter-API
I try to get into it with PHP on my localhost. First i just want to do some basic stuff. I use the twitter-api-php by J7mbo and got everything as in the examples. I got my Costumerkey (which is the Api-Key, right?) and the access-token. But i always get an empty result 
My Code: pastebin-link
The Result output looks like this: pastebin-link
So there seems something to happen, but i got no clue where my mistake is. Can you help me out?
