You're actually very close. I would just change a couple of things.
First of all, you don't need @data as well as @rows. $element is aliased to
each element in the array as it loops, so you can re-assign right back into
the same array when you split. This will cause the loop to independent of
the order in which it reads the elements from @rows, which means you don't
need '$i' as well.
Second, when you create your nested array, you need to use [].
sub quotes
{
my $content = get_content();
my @rows=split/\n/,$content;
foreach my $element (@rows)
{
$element=[split(/,/,$element)];
}
return @rows;
}
As a matter of personal style, i prefer to take advantage of the default
variable, since i find it easier to read, though others may not:
sub quotes
{
my @rows = split /\n/, get_content;
$_=[split /,/] for @rows;
return @rows;
}
Or if you want to be COOL like Bob ;)
sub quotes {map {[split /,/]} split /\n/, get_content}
And i think in this case using 'map' would be okay, since it's going to have
to loop over the entire array anyway. Am i wrong ... ?
