Question

I have an array that is a member of a structure:

$self->{myArray} = ["value1", "value2"];

And I’m trying to iterate over it using the following code:

my @myArray = $self->{myArray};
foreach my $foo (@myArray){
    #Do something with the using $foo
    ...
}

The problem is that the ‘foreach’ loop is executed only once (when I would expect it to execute twice, since @myArray has two elements: “value1” and “value2”).

When I check the @myArray array size, I get that its size is 1. What am I doing wrong in this code?

Answer 1

I believe that:

$self->{myArray} returns a reference.

You want to return the array:

@{$self->{myArray}}
