How to Code a Slot Machine Game Using PHP

A good working knowledge with PHP is useful for any computer programmer. According to Coding Dojo, PHP remains one of the most in-demand programming languages of all time because it's easy to understand, and offers tons of advanced features for experienced programmers. There are several tutorials online that you can review in order to get a basic, working knowledge of PHP and if you want to create a simple game using the language, check out the code below.

Slot machines are among the most popular games around the world. Despite being an old form of entertainment, with the very first machine being manufactured back in 1899, slot machines are still super popular in casinos. The aura of visiting a casino is still very attractive with the Review Journal reporting that casinos in Las Vegas raked in a total of $11 billion in 2016, besting its figures in 2015. The online gaming industry is even more popular with Statistic informing that in 2015 the market was worth $37.91 billion dollars with it projected to surpass $59.79 billion by 2020.

The gaming business remains successful because the competition stays strong. This means that gaming providers constantly upgrade their systems, and regularly offer new titles. One of the biggest trends online currently can be seen utilized by Spin Genie with their many variations of slot games. These adaptations demonstrate how online gaming is always developing in order to keep offering something new to the gaming public. Fun and new concepts keep players entertained, which is why online casinos are among the most successful entertainment platforms today. If you want to become a successful developer of slot games someday, you need to be able to walk before you can run. Here's a simple code that you can use as framework for your future builds.

Developing a three-reeled slot machine game with PHP…

The code was originally posted on IBM's Developer Works page. Check out the site if you want to learn how to create other games.

Now, let’s begin. First, let us establish the game's user interface:

$faces = array ('Figure1', 

Of course, you can use any image you want for the figures: faces of cartoon characters, dragons, musical instruments, anything.

Then, you need to declare the combinations of winning reels. In the slot machines of old, three images must match a payout line. That said, write the code like this:

$payouts = array ('Figure1|Figure1|Figure' => '10',
                  'Figure2| Figure2|Figure2' => '20',
                  'Figure3|Figure3|Figure3' => '25',
                  'Figure4|Figure4|Figure4' => '35',
                  'Figure5|Figure5|Figure5' => '50',
                  'Figure6|Figure6|Figure6' => '200');

if (isset($payouts[$result1.'|'.$result2.'|'.$result3]))
  // give the payout

Now, you need to make the reels spin like a real slot machine.

$wheel1 = array();
foreach ($faces as $face)
  $wheel1[] = $face;
$wheel2 = array_reverse($wheel1);
$wheel3 = $wheel1;

That's it! With this code, you will be able to write games that have all the elements of a working slot machine.
