How can I retrieve data loaded into an array within a foreach block?
The array is defined outside the foreach block and is not the indexing
array of the foreach loop.
I was about to ask the same question as Alex did.
A few other remarks:
my @lines = ();
my @line = ();
It seems like there is no need to define those variables outside the loop.
my @lastnames = ();
loaded into @lines a file
Why? If there is no particular reason to do so, the better practice is
to read the file line by line.
Please consider this code:
my $file = 'data.txt';
open my $fh, '<', $file or die "Opening $file failed: $!";
my @lastnames;
while ( <$fh> ) {
my @line = split /\t/;
chomp @line; # if the record has no further elements
push @lastnames, $line[1];
}
