in thread comparing array elements

To compare two strings for equality, one uses eq, not =~ (although, if the words just contain letters, it would work too).

    yep, but this loop seems to be comparing every position in the first array to every position in the second, not one at a time! How can I do this?

      Why do you need two for-loops? Wouldn't one work?

      my @array1 = ('test', 'text', 'next');
my @array2 = ('text', 'test', 'next');
for (my $i=0; $i < scalar(@array1); $i++) {
    if ($array1[$i] eq $array2[$i]) {
        print "$array1[$i] matches\n";
        }
    }

      How's that possible? You index both arrays with the same key.

        ok, you're right.. its not working - it thinks both arrays are the same
