Let us consider a code of checking the age first. It checks whether the ‘age’ is given in the form or not. If it’s not given, then it says ‘not mentioned’. When it’s given it just spits out the age. Very basic thing we normally did when php 7 had not come.
$age = isset($_GET['age']) ? $_GET['age'] : 'not mentioned';
As usual it’ll give an output of – ‘not mentioned.’ Now we write this code with the age given.
Can we Adapt SMS into MAIL?
Now we’re going to do an impossible task.
Are you prepared?
Can we start?
This chapter is about the adapter pattern. It’s one of the design patterns that you’re currently on. Let us start with a real world example.
You know that internet connection is absolutely necessary for sending emails. Is it true in the real world? You’d say, well, I know that. An internet networking is a must.
Why I let readers download my books absolutely FREE
People may doubt whether my motives for letting readers download my books absolutely free are altruistic-you may doubt that behind this big-hearted decision I probably hanker for publicity.
You are always welcome whatever way you perceive me. Good, bad, or ugly.
The true motivation stems from one single principle-knowledge should be free and remain accessible to all. Besides that, I believe only true knowledge can save us from this ubiquitous and omnipresent poverty.
So through the Leanpub platform, you may either download my books absolutely free or you may pay any amount you wish. The choice is yours.
I am a full-time writer, so I write books to put bread on my table. If you have money, pay any amount you want to, it starts at 0.99 Dollar; however, if you have no money, don’t worry, download the books absolutely free. As long as Leanpub allows this, it’s fine. If they stop that, I will start it right from here.
Now, I plan every book in a way so that it relates to a series of video stream where I explain the concepts audiovisually.
I would request you to subscribe to my YouTube channel and share it with your friends for one single reason. It indirectly helps me going this way-my own “FREE” way.
Happy reading. Happy watching. Happy coding.
Let us see how Responsibility can be Unchained!

What is behavioral design pattern? They are a type of design patterns that generally identify communicating objects.
