I've recently written a number of articles about the Perl hash construct (or "Perl array hash"). In an effort to try to organize the Perl hash tutorials I've written, I've created this article to help link them all together.

The hash in Perl - introductory tutorials

Here are the Perl hash introductory tutorials I've written:

• Perl hash introduction/tutorial
• Perl foreach and while: how to loop over the elements in a Perl hash
• Perl hash add - How to add an element to a Perl hash
• How to print each element in a Perl hash

The hash in Perl - advanced tutorials

Next, here are a few slightly more advanced Perl hash tutorials. (It's not so much that they are advanced, but more that you won't need these as much as the others.)

• How to see if a Perl hash contains a key
• How to delete an element from a Perl hash by key

The hash in Perl - hash sorting tutorials

And finally, here are links to several "Perl hash sorting" tutorials:

• Perl hash sorting - Sort a Perl hash by the hash key
• Perl hash sorting - Sort a Perl hash by the hash value

Perl hash tutorials - summary

I hope this collection of "Perl hash tutorials" is helpful. The Perl hash/array is a really powerful construct when used properly, so I wanted to make sure I covered it thoroughly.
