Project 3: Slot Machine. Slot machines are the most popular game in modern casinos. If you’ve never seen one, a slot machine resembles an arcade game that has a lever on its side. For a small fee you can pull the lever, and the machine will generate a random combination of three symbols.

Stay tuned for additional content in this series.

In this article, we build an inventory-management system and note-taking scripts for your role-playing games, while working on the interactivity of your PHP scripts. We also build an image-based ID card generator and get your feet wet performing image manipulation with PHP. We will create a poker-hand evaluator, a slot-machine generator, and a casino bank, allowing you to practice some trickier PHP logic. We will take our word-game scripts one step further working with a difficult logic by building a complex anagram generator, a crypto solver, and more.

These scripts are a little harder than the scripts from Part 1 and Part 2 because they accomplish a lot more. The code archive for this article contains the full source code for each script we will discuss.

As in Part 1 and Part 2, we're going to be blazing through these scripts pretty fast. If you haven't run through Parts 1 and 2, you should do so before starting this article.

Basic inventory-management system

Having already put together a script to manage character stats, let's take the script one step further and add some basic inventory management. Using this script, we keep track of spent ammo, burnt torches, and found items (see Listing 1). Rather than try to lay out all the items you might ever find, we create two input fields — one for the name of the item and one for the item count: <input name='newitem' /> <input name='newcount' />. When the script is submitted, we want to add the new item to an inventory array and save the array along with the character sheet. Then we walk the inventory array and create new input fields to hold the items.

Those input names may look weird, but by structuring them in this fashion, PHP will create the 'inventory' array automatically, complete with name-value pairs. See the script archive to see how this is all pulled together.

A simple note-taking script

It's helpful when playing an RPG to scribble down some notes. The notes are less helpful when you can't figure out where you wrote down the important parts. Let's put a script together that helps store and find game notes.

Taking a note requires only two form fields: <input name='title' /> <br /> <textarea name='body'> <br />.

As with the character sheet, the notes are added to an array, serialized, and stored in a text file. As you save the note, you'll analyze the words. The word count is also stored in the same text file. To make this easy, replace anything that isn't a letter or number and lowercase the whole note (only for the analysis): $analyze = preg_replace('/[^0-9a-zs]/', strtolower($_POST['body']));. Then split on white spaces and push the note ID into the word-count array for each word.

You can see how to retrieve individual notes, or notes by keyword, by trying out the test script or looking in the code archive.

ID-card generator

If you're playing a modern-era game, having a physical ID card for your character can impress your friends and add a sense of realism to a game. You're going to put together some PHP image-manipulation code that will allow you to create an ID-card image suitable for lamination. To start, we need a basic image to use as an ID blank. We will use this crude ID blank I pulled together for the example.

Figure 1. Example ID blank

https://bittree.amebaownd.com/posts/15810128. We need a basic form to collect the fields for the ID card (Name, Authorization, Home, Birth date, Hair and Eye color). Then we need to push those values as strings into the image. Some of this takes trial and error to get right, as you determine the right places to start and stop text: imagettftext ( $img , 40 , 0 , 600 , 200 , 0 , 'tarzeau_-_OCR-A', $_POST['name'] );. If you've done everything correctly, you should be able to fill out the form and get something like Figure 2.

Figure 2. Example ID filled out

The font specified is included in the code archive, and the source image is 300DPI. Getting the font and ID card working can be tricky on some systems, but the source in the script archive calls out the problem areas.

Tile-based map generator

Early computer games used tiles to create game maps. The same basic tile approach is still used today in some circumstances. Let's put together a script to generate a basic map. This map won't be very big, but we can use the same principles to create much larger maps, of varying detail. To start, create a few different terrain types and throw together some really rudimentary map tiles to represent each terrain type.

Figure 3. Basic terrain types

Now that we have basic terrain types, you can imagine what comes next: We create an array of map tiles for each row. But we will get poor results by just picking the terrain types randomly and shoving them into arrays.

Let's make a map that's 20 tiles in size. When picking a terrain type, consider the surrounding tiles when making decisions. Look at the four closest-known tiles: the last tile in the current row and the three tiles directly above the current tile. We can set up complex rules to govern how terrain is generated, but for now, start with something simple: Add the terrain types of the four closest tiles to the array before picking them randomly. The more times we add the previous terrain types, the more likely we will get homogeneous regions. The result is something like Listing 3.

Once we have a map array, we iterate through each row and column, including an image for each terrain type. Try
