Perl push values into Multi Dimensional Array

Question

I have created a simple multi-dimensional array:

my @arraytest = ([1, 2, 3],[4, 5, 6],[7, 8, 9]);
print "Array - @$_\n" for @arraytest;

Output:

Array - 1 2 3 
Array - 4 5 6 
Array - 7 8 9

How do I push "10, 11, 12" to the next element in this array?

You need to create an array reference, and push that as the next element. The easiest way is to make an anonymous array ref.

push @arraytest, [10, 11, 12];

Your output now looks like this:

Array - 1 2 3
Array - 4 5 6
Array - 7 8 9
Array - 10 11 12

The important part is that your @arraytest is an actual array (not a reference), so you can just operate on it directly with push, pop and so on.

See perllol for more details.

The question could also read as push that string, then the answer would be push @arraytest, "10, 11, 12";.
