Each item in the array is one string. You need to read
this book. I've seen free PDFs for that around the web. You might also try
this page. You need to know about scalars and arrays as basic types, how to write loops, and probably everything else. So just start with a beginner book and work through it.
my @samples= ('a,b,stuff', 'b, c , more stuff');
foreach my $line (@samples) {
# work with $line here
}
See
Foreach Loops in the Perl documentation.
