READ what I wrote. I said nothing about the question, if your code works
or not - but I doubt, that you really *know* what the difference is between:

if($six0[$item][2] = $six0[$track][2])

and

if($six0[$item][2] == $six0[$track][2])

Do you? Can you explain, why your code uses the assignement and not the
comparison?

Some how it feels if I already explained this a dozen times and I just
forgot that...

I did. And you don't see any difference in readability above in your
version and my formatted version?

Also see here:

<http://arnowelzel.de/wiki/lib/exe/js.php>

But this does not mean, that such code is *readable* nor that I
recommend to write code this way.

In this special case (<http://arnowelzel.de/wiki/lib/exe/js.php>) it is
a "compressed" JavaScript to save bandwidth and lower the number of HTTP
requests needed. But this is constructed dynamically by js.php which
takes the local JavaScript files and creates a big "compressed" version
of them in one single block.

But for scripts which remains on the server and will never be
transmitted to the client it should be *readable* for *humans*.
