Perl, or Practical Extraction and Reporting Language, is an open source programming language. It is often used for creating CGI programs and other web scripts. It was specifically designed for processing text, which makes it useful when writing web forms. If you want to use this popular programming language to help you process piles of text through your website, you’ve come to the right place.

Perl: Bon Voyage Lists and Hashes

James Payne 17882

Thanks for stopping by for our final article on Perl lists and hashes. This marks our twelfth issue on the subject (at least until we get to some more advanced techniques later on) and in it, we will look at a few of the functions for manipulating two-dimensional lists, how to create lists with more than two dimensions, and finally, how to make a hash full of lists, which is really quite a handy tool.

Perl: Number Crunching

James Payne 53093

In this tutorial we will look at working with numbers in Perl. We'll cover the basics, such as integers and floating points, and end with the more advanced topics, like converting strings to numbers. With Perl you don't need to be a math genius. These simple tips can help you be a virtual Einstein.

Perl: More on Lists and Hashes

James Payne 25327

Welcome to the first part of what should be the final two articles in our series on working with hashes and lists in Perl. This makes our eleventh article in the series and in it, we will wrap up the intermediate ways of working with hashes and lists. We'll learn to add rows and columns to a two-dimensional list, replace them, create multi-dimensional lists, and write hashes and files to lists, then open and read from those same files over the next two articles.

Perl: Dimensional Lists

James Payne 34255

Thanks for stopping by to read my tenth installment on working with hashes and lists in Perl. In our previous article we learned how to find out if a hash holds a specific value, does not hold a specific value, or holds any value whatsoever. We further learned to create our first two-dimensional array and then worked to better understand how exactly a two-dimensional array works. Which is where we pick up in this article.

Perl: A Continuing Look at Hashes and Multidimensional Lists

James Payne 35012

Welcome to the ninth installment in our look at working with hashes and lists in Perl. In our previous article we learned how to add records to a hash, replace them, and delete the values inside of them. In this article we will learn how to check whether records reside within our hashes, write the data within a hash to a file, and create multidimensional lists.

Perl: Another Round with Hashes

James Payne 19958

Welcome to the eighth episode in our series on Perl Lists and Hashes. In this article we will discuss how to add a record to a hash, as well as how to remove a record from one. We will also cover how to check to see if a record already exists in our hash, how to write the data contained in one to a file, and quite possibly go over the basics of multidimensional lists.

Perl Hashes

James Payne 42213

Thanks for stopping by for this seventh part in the series on Perl Lists and Hashes. Here we will discuss working with a new way to store data known as a Hash. We'll cover the basics, such as how to create them, and how to locate data within them. You'll learn to add records, remove records, and much more. If there is time, we will also cover multidimensional lists.

Perl Lists: A Final Look at List::Util

James Payne 21190

Welcome to the sixth part of our series on Perl Lists. Here we will cover the remaining four List::Util subroutines: min(list), minstr(list), shuffle(list), and sum(list). We'll learn how to manipulate lists using these subroutine in various intended and unintended ways.

Perl Lists: Utilizing List::Util

James Payne 29467

In this fifth part of our series on Lists, we will cover the List::Util module, which gives us seven handy-dandy subroutines with which to manipulate our lists. If we have time, we'll also cover multi-dimensional lists in more depth (we briefly covered them in an earlier article).

  04-07-08 

Perl Lists: The Split() Function

James Payne 145121

In this fourth part of our series on Lists, we will start off with the split() function and hopefully end by covering hashes. In our last article, we covered the splice() function, which we used to add, remove, and replace elements in a list. We then used it to create variables and arrays. We also worked with some operators to repeat a list and to create sequential lists.
