Array construct and foreach loop

perl_5eeker has asked for the wisdom of the Perl Monks concerning the following question:

Hello experts I am trying to run foreach loop on each element of array which looks like below (from Dumper) $VAR1 = 'abc def xyz'; foreach considers the above as a single element, I have tried splitting the array but I am missing something simple here, your help is much appreciated.

What you've shown is a string, i.e. a scalar, not an array. Using split can turn it into a list; you can populate an array with a list, or you can iterate over it directly: `#! /usr/bin/perl use warnings; use strict; my $string = 'abc def xyz'; # my @array = split ' ', $string; for my $part (split ' ', $string) { print "<$part>\n"; }` [download] `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

split

#! /usr/bin/perl
use warnings;
use strict;

my $string = 'abc def xyz';
# my @array = split ' ', $string;
for my $part (split ' ', $string) {
    print "<$part>\n";
}
