Yea, using slices can accomplish this too. But if you're going to be using slices or a fixed number of elements on the left hand side you should also be using the third argument to split($delim, $input, $count) to tell split to only produce so many outputs. If the input string would split into more than two pieces in your original code you would end up overflowing into @arr4 and losing results from the second split.
