在perl中訪問數組中的單個元素的問題

Question

我在解析數組時遇到問題。我已經使用

print Dumper($variable) 

得到

$VAR1 = [ 
      'joshn', 
      'taylor' 
     ]; 

我需要得到各個元素Josh和泰勒。我如何獲得它？

Answer 1

我想$variable是一個裁判的陣列，然後

for(@{$variable}) { 
    print $_, "\n" 
} 

EDIT：

my @array = @{$variable}; 
print $array[$#array]; 

Answer 2

# get last element 
my $last = $variable->[-1]; 

# get first element 
my $first = $variable->[0]; # cryptic equivalent: $$variable[0] (don't use it) 
# get second element 
my $second = $variable->[1]; # also $$variable[1] 

# same effect as above 
my ($first, $second) = @{$variable}; # or @$variable for short
