implode() invalid arguments

Question

When I try to run this code:

$arraytest = implode(", ", $array['playerList']); print $arraytest;

I'm getting this error:

Warning: implode() [function.implode]: Invalid arguments passed in /home/crafter/public_html/index.php

It's supposed to fetch info about my minecraft server.

I did var_dump() on it and it responded NULL. I automatically assumed it was an array since I got this script from the bukkit forums...

Do `var_dump($array);` and I'm sure you'll find your answer. — Mike, Feb 06 '13 at 20:50

$array['playerList'] must be an array, it probably isn't.

$array['playerList'] probably isn't an array. You can check with: echo gettype($array['playerList']);
