PHP Puzzles: Grid Mapping

By Sherri Wheeler

In our last issue, we plotted a list of compass directions onto a grid to determine a destination x,y point. In this article, we look at generating a simple output for a colored grid.

PHP Puzzles: Destination Point

By Sherri Wheeler

In our last issue, pruned a set of directions to remove values that cancel each other out. It was an exercise in cleaning data, an often crucial step before importing it or processing it elsewhere. In this article, we look at plotting those directions on a grid.

PHP Puzzles: Improved Directions

By Sherri Wheeler

In our last issue, we simulated population growth—a component of many popular games. In this article, we look at pruning redundant items from a list of directions.

PHP Puzzles: Calculating Population Growth

By Sherri Wheeler

Each installment of PHP Puzzles presents a small coding exercise typical of those we might encounter in a job interview, or on a coding challenge website. In the following month, we’ll look at a couple of possible solutions for today’s puzzle.

PHP Puzzles: Writing a Dice Roller

By Sherri Wheeler

In our last issue, we looked at a problem from game development—generating random loot with different rarities. We saw multiple solutions, including a common technique used in many games. Our new puzzle asked us to calculate dice rolls for tabletop games.

PHP Puzzles: Random Loot

By Sherri Wheeler

In our last issue, we looked at multiple solutions for the Fibonacci math problem. We saw a common recursion gotcha when one of our solutions caused PHP to timeout on modest inputs. We then took a more fun direction and presented a problem from game development: randomizing the quality of loot generation. Let’s look at loot quality and then pose another game related puzzle.

PHP Puzzles: Calculating Fibonacci Sequences

By Sherri Wheeler

Each installment of PHP Puzzles presents a small coding exercise typical of those we might encounter in a job interview, or on a coding challenge website. In the following month, we’ll look at a couple of possible solutions for today’s puzzle. In our last issue, we solved the very common Factorial math problem to get ourselves warmed up. We looked at an iterative and a recursive solution. I then ask readers to solve the similar Fibonacci problem.

PHP Puzzles: Factorials

By Sherri Wheeler

Each installment of PHP Puzzles presents a small coding exercise typical of those we might encounter in a job interview, or on a coding challenge website. In the following month, we’ll look at a couple of possible solutions for today’s puzzle. Perhaps one of the most common coding puzzles, I recall this one from high school computer class&msdash;calculating a factorial.

The Business Of PHP

By Sherri Wheeler

Among the many strategic decisions a business needs to make, one which we as developers are involved with is the choice of tech stack—the tools and technologies used for software development. When choosing a backend language, PHP presents its list of strengths and weaknesses; this article examines these from a business perspective.
