Perl foreach loop arrays, simple question

Question

A really simple question, but it really bothers me.

foreach $ val (@ {$ obj-> something ()}) {
    # this works
}

@array = $ obj-> something ();
foreach $ val (@array) {
    # this does not
}

What I need to do to do the second job (i.e. assign an array separately), I used the first form as a fair bit, but I don’t understand what it does differently.

Answer 1

Maybe:

@array = @{$obj->something()};

In the first example, it looks like it $obj->something()returns a reference to an array, you need to dereference it.

In addition, you must really use strict;and use warnings;, and declare your variables as

my @array = @{$obj->something()};
foreach my $val (@array) {
    # this does not
}
