There's no need to assign something to itself just to test it. The
test:

if ($six0[$item][2]) ...

is probably what you want, though the assignment will create
$six0[$item][2] if it does not already exist, so the two are not exactly
the same.

You can make the code more self-documenting by using defined constants
for these indexes:

define('FLIPSIDE', 1);
define('LABEL', 2);
...
if ($six0[$item][LABEL]) ...

or by using string indexes directly (e.g. if ($six0[$item]['label']) ...).
