Yesterday I created a post on OOP and had to split it in two to avoid making it too long. Today, I am going to finish up the remaining part before starting other stuff! So, let us get started here.
Controlling Visibility Through Inheritance With private and protected
While writing code using OOP, you can use private and protected visibility modifiers to control what gets inherited. Attributes or methods declared as private will not be inherited. If an attribute or a method is marked as protected, it will not be visible outside the class (like private) but will be inherited. Example:
Functions exist in most programming languages and they separate code that performs a single well-defined task. This makes it easier to read and reuse the code. A function is a self-contained module of code that prescribes a calling interface, performs some task and optionally returns a result.
There are several reasons to write your own functions in PHP; for instance if you want to perform a task that other built-in functions cannot help you do. Let us quickly look at an example of a function call before we do function definition.

Hello! One thing you will hear everywhere you go as a coder is code reuse – the idea that if someone has already written some code that you need, you might want to consider using it instead of spending so much time writing from scratch. You could choose to repeat the process but your boss might not like it very much!
Hi! I am back from a serious headache and today am going to talk about regular expressions. The idea is to validate data submitted by the users of our online store. This will help us stop taking in invalid emails, or stuff like that. Also, using a new page created for feedback submission, we would like to send the message to respective departments depending on which Â words our customers mention in their messages. Let us get started.
Here is my feedback page:
Hello! Today, am just going to step a side(from code) and share with you some of the coolest things I have in my pocket! First of all, let us both agree that the web is too big to beat and you could spend the rest of your life roaming around in search for the right information!
I don’t know about you but I face information overload quite often and I end up not getting the answers to my questions even though I have the whole day to sit in front a computer. You are probably thinking, ‘what about just opening a browser and typing some key words into Google ?’ Yeah, trust me, you can do that and still find nothing useful.
Hello! Today, I want to use arrays to improve our shopping cart and find out more about them as we go a long! This post is going to be split into two: Part 1 and 2. You want read them in parts or in full. There are basically two types of arrays in PHP: numerically indexed arrays – where indices start at zero by default and non-numerically indexed arrays – where the keys can be set to whatever you deem meaningful. Let us start with numerically indexed arrays:

Hi! After adding some functionality to our shopping cart, I am going to do something different today: storage. Assuming we want to collect all the orders from customers and store them in a file somewhere for later use, we can easily create a file and write and read to and from it. I have altered the original look of our simple cart by adding a new input area for shipping address: Let us look at it now.
Hi! I know you are probably asking what the heck is he doing? I will be honest here, this is not a tutorial but a simple quick fix to a problem I faced last night. I was invited by an author to take part in the so called blog hopping. One of the requirements was to find at least five other authors with blogs to join the adventure. So, I asked myself, how could I make this as much fun as possible and learn something at the same time?

After completing my first two challenges from Mozilla P2PU (HTML and Twitter API programming), I have decided to continue the amazing journey of learning new things. So what is up next for me? The answer is learning PHP. What does PHP stand for? It stands for PHP: Hypertext Preprocessor – which is a recursive acronym.
The next question you might be asking is: what the heck is PHP? I will make it simple enough to understand and then leave the rest to PHP on Wikipedia . So, php is an open-source server-side scripting language designed for web development to produce dynamic web pages. Something worth mentioning here is Rasmus Lerdorf – the creator of PHP (Give credit where it is due)!
