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.

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, 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.
Today, I am going to explore farther or deeper into what we can do with what Twitter API calls returns to us. I will make the whole post a step-by-step tutorial so that anyone interested in trying the codes out can do so with ease. So, let us get started.
