I'm wondering why this is.
$data = ;
$array = explode(,,$data);
$count = count($array);
$count will = 1
$data = Test;
$array = explode(,,$data);
$count = count($array);
$count will = 1
$data = Test,Test;
$array = explode(,,$data);
$count = count($array);
$count will = 2

$array has 1 element:
Not sure why it does it, but doesn't seem to be a huge deal. I'm guessing it's
