you might want to think of using a hash here
instead of a straight array, hence
my %phone_book = (
Fred => 0123,
John => 4567,
Bill => 8901,
);

hence
my $name ;
#you could do this as a numeric compare to make sure it is a 1
if ( $selection eq 1 ) {
chomp(my $number = <STDIN>);
print "$name number is : $phone_book{$name} \n"
}

which is a bit peculiar, but you may find that with a 'hash'
it will be easier to deal with....
then you can look at more complex structures
