如何在Perl哈希表中存储多个值？

直到最近，我已经使用相同的键将多个值存储到不同的哈希中，如下所示：

%boss = (
    "Allan"  => "George","Bob"    => "George","George" => "lisa" );

%status = (
    "Allan"  => "Contractor","Bob"    => "Part-time","George" => "Full-time" );

然后我可以引用$ boss(“Bob”)和$ status(“Bob”)，但是如果每个键都有很多属性，那么这样做会变得笨拙，我必须担心保持哈希值同步。

有没有更好的方法来存储多个值在哈希中？我可以将值存储为

"Bob" => "George:Part-time"

然后拆分弦，但必须有一个更优雅的方式。

解决方法

这是 perldoc perldsc的标准方式。

~> more test.pl
%chums = ( "Allan" => {"Boss" => "George","Status" => "Contractor"},"Bob" => {"Boss" => "Peter","Status" => "Part-time"} );

print $chums{"Allan"}{"Boss"}."\n";
print $chums{"Bob"}{"Boss"}."\n";
print $chums{"Bob"}{"Status"}."\n";
$chums{"Bob"}{"Wife"} = "Pam";
print $chums{"Bob"}{"Wife"}."\n";

~> perl test.pl
George
Peter
Part-time
Pam
