Is there any function for hash like push function in arrays

[PhoenixInsilico]

I am stuck in program which need to build a hash of unknown number of keys which we will enter or give. If there would be a push function we can make loop and increase its size.But how will be it possible with hash.

This doesn't make any sense. When you say "an unknown number of keys" what are you talking about?

I mean:

$hash{$key}=$value;

Why would you need a push?
