Same in PHP:
$sku [$id] [$line] [$price] = 99;
if $sku is an array. If unsure, initialize it as one:
$sku = array ();

$first is a string, i.e. $first [$n] accesses the $n'th character in the
string "Elementary".
$second is a string as well. You use it as index in the string, so it is
automatically converted to an integer: "Middle" -> 0
So you assign "pass" to the first character of $first.
And as you can only assign other single characters to a single char, the
first char of "pass" is used.

That should be a lowercase 'p' (see above)
Summary: You thought too complex and thus stumbled over another feature
of PHP :)
