Iteration by indexing works *iff* all your indexes are numeric and
sequential. Your for-loop won't work on non-sequential arrays like this:

array(
0 => '123,45',
1 => '123,45',
9 => '123,45'
);

because count() will return 3, meaning that the last element of the array,
with index 9, won't be touched. Nor will it work on:

array(
-1 => '123,45',
0 => '123,45',
1 => '123,45'
);

as your for-loop has a hard-coded start value of 0. Nor will it work on:

array(
'a' => '123,45',
'b' => '123,45',
'c' => '123,45'
);

because the keys aren't numeric. Iván's foreach-loop will work on all of
these three examples.
