Re: Load hash from a scalar

I want to load the value from scalar variable to a hash

Example:
my $a = "a, 1, b, 2, c, 3";

Now, I need to create a hash %b, which holds values like
%b = { a => 1, b => 2, c => 3 };

$ perl -le'
use Data::Dumper;
my $a = "a, 1, b, 2, c, 3";
my %b = $a =~ /[^, ]+/g;
print Dumper \%b;
'
$VAR1 = {
'c' => '3',
'a' => '1',
'b' => '2'
};
