Parse error: syntax error, unexpected '[' with php how do I fix it?

Question

Good Evening, I have been trying to start a Clubpenguin Server, I am using xampp control-panel v3.0.2 for the reason that it still has the shell option. The problem I run into is that when I run the PHP file it throughs errors. I have ready a couple of options: I tried restarting xampp a couple of time but it does not seem to be functioning. I also tried changing [] to array() and as soon as I did it said line 43 was wrong (previously line 76 was wrong). I am not completely sure how this work so if anyone could help it would be greatly appreciated.
