如何在不了解索引的情况下将值推入数组的哈希中?

How do I push values into a hash of arrays without knowing anything about index?

我该如何实现?

推荐答案

这将通过"TEST1"键将值添加到存储在哈希中的数组的末尾.

This will add value to the end of array stored in hash by "TEST1" key.

push( @{ $TEST { TEST1 } }, "some value "); 

我已使用@{...}取消引用数组引用.然后，Perl会自动创建内部数组引用.

I've used @{...} to dereference array reference. Perl creates inner array reference automatically then needed.
