Object Oriented PHP for Beginners

php_elephant
I think the Idea with this elephant logo is that you’ll associate PHP with smiley “cartoony” things and approach it with optimism. While I’m certain you can learn PHP, I’m not so fond of such attempts to obfuscate the fact that PHP is a language that will require some dedication to get your head around. Or maybe they just like elephants?

Here’s an excellent tutorial that introduces the concept of Object Oriented Programming (OOP) in PHP. It is written lucidly but may be a little confusing if you don’t already have some basic familiarity with the PHP language.

Here’s another tutorial if you find that one a bit much.

<?php
 
class MyClass
{
  public $prop1 = "I'm a class property!";
}
 
$obj = new MyClass;
 
echo $obj->prop1; // Output the property
 
?>

The Codeworx Challenge

Screen Shot 2015-12-13 at 9.46.28 PMThe Codeworx Challenge is an annual competition here in New Zealand that rewards innovation and initiative. In groups of up to four people, students were tasked with solving a real world problem this year using a Raspberry Pi and code. The results were outstanding as you can see for yourself on their website.

Industry professionals were also impressed if this article from the New Zealand Herald is any indication.

Create Stylish Vector Portraits

digitalartsonline.co.uk have excellent tutorials. Here’s one that shows you how to make a vector illustration from a camera image. It uses both Photoshop and Illustrator and is a good way to experience the strengths of either.

In this tutorial, Eelco van den Berg lets you behind the curtain to see how he creates his incredible vector portraits by turning a photo into a ‘poppy’ vector illustration.

It says that it could take 3-4 hours so you may want to make a cuppa.

photoshopessentials.com

photoshopessentials.com has a lot of well developed tutorials. I find them easy to follow even though some of the tutorials are for different versions of Photoshop than the one I have a license for. Regardless, most of the features are the same as Adobe is one of those companies who release new versions often despite very little change (something I find annoying).

This tutorial on how to use the Free Transform tool is a great place to start.

Billy Blob

I’m very happy to introduce you to freelance animator and web designer Billy Blob. He’s been putting out interesting work for over 15 years and was one of my inspirations while I was at uni. HIs website is so different from all of these boring “themey” designs (like … ahem …  the one for this site). He’s an artist who adopted a digital medium, as opposed to a tech guy having a crack at being artsy.

a bumblebee contemplates the meaning of his life with an optimistic butterfly.

Here’s another video that goes with it.

OOP and The Internet of Things

This article by author  brings up an important subject that will no doubt become more relevant as the public becomes more familiar with “The Internet of Things“. Matt points out that the conceptualization inherent with Object Oriented Programming is what makes IoT possible.

“It can safely be said that the object has been the driving force in the programming industry for a very long time and will continue to be so for the foreseeable future. The evidence to support this statement is pretty compelling! Today, just about every major software development methodology is based on objects. As a result, virtually all programming languages, scripting languages and application designs are object-oriented or object-based.”
