Clam down. I miss-read the line, it's not a question of not bothering.

No, that's not what happens. The condition is true if and only if
$six0[$track][2] is considered to be true (i.e. not null, false, 0, 0.0,
"", "0", array() or an empty object).

As a side effect, one or more elements of $six0 have their [2] component
set to $six0[$track][2] depending on exactly what data there is in the
array.

Two other points: (1) you access outside the array but running the loop up
to and including $max, and (2) using '0' when you mean 0 is confusing.
It works, but it's not as clear as it should be.
