数组变量以 @ 符号开始，元素放在括号内

简单举例如下

#!/usr/bin/perl
@names = ("a1", "a2", "a3");

print "\$names[0] = $names[0]\n";
print "size: ",scalar @names,"\n";

$new_names = shift(@names);
print "\@names  = @names\n"."弹出元素为 ：$new_names\n";

$namess = "a1,a2,a3";
@namess  = split(',', $namess);
print "@namess\n";

运行结果如下所示

Perl中哈希变量以百分号 (%) 标记开始

访问哈希元素格式：${key}

简单举例如下

#!/usr/bin/perl
%data = ('google', 'google.com', 'runoob', 'runoob.com', 'taobao', 'taobao.com');
 
print "\$data{'google'} = $data{'google'}\n";

@names = values %data;
 
print "$names[0]\n";
