Re: Re: array confusion

Following on from the foregoing to achieve a result from the second example the same as the first you could do:

my @look_for = ($name,$nerd,$noodle,$froodle,);
foreach my $item (@look_for) {
$item =~ s/$i_seek/ /g;
}
($name,$nerd,$noodle,$froodle,) = @look_for;

But this looks a little clumsy - maybe there's a better way?

That is one way. It assigns the list of values contained in @look_for back to the original scalar variables. Another way is using references. `# Assign to @look_for, references to $name, etc. # Note: \($x, $y, $z) is the same as (\$x, \$y, \$z) # because the reference symbol binds to each element in # the list. my @look_for = \( $name, $nerd, $noodle, $froodle,); foreach my $item ( @look_for ) { # notice how I dereference $item so that we get # to what it points to. $$item =~ s/$i_seek/ /g; }` [download] That will do what he's looking for, unless, of course, we've now broken other uses of @look_for in his code where his code might be expecting @look_for to contain scalar values rather than references to scalar variables.

my @look_for = \( $name, $nerd, $noodle, $froodle,);

foreach my $item ( @look_for ) {

    # notice how I dereference $item so that we get
    # to what it points to.

    $$item =~ s/$i_seek/ /g;

}
