In this blog, I will try to help you understand the 'object-oriented' programming paradigm. Object-oriented programming can be applied in various programming languages, but in this article, examples are given in PHP.
People who practice object-oriented programming can break down similar components into code; this ensures, among other things, that you do not have to repeat code. After all, by dividing the code into objects, you can use it multiple times.
So what exactly is an object? Below is an example of an object written in PHP.
We can create the object above to use the functions contained within it. We could do this in the manner shown below.
We have now created a person named Henk, aged 21 and from the Netherlands. Next, we can call the functionalities contained in the Person object to use them.
Thus, the following result is obtained from the two lines below:
Henk says: I am producing a sentence now.
Henk says: My name is Henk.
If we wanted to create an extra Person, we could accomplish this by simply using the Person class again. This avoids having to repeat ourselves, which results in time savings and, moreover, cleaner and clearer code.
Another advantage of object-oriented programming is that if you make a mistake in the code and this code is repeated in multiple places, you do not need to make adjustments in multiple locations. In the case of objects, you only need to modify the object containing the error, meaning that the other objects using it will immediately be corrected of the potential error.
Partly due to the above advantages, object-oriented programming is a popular and widely used method. If you have any questions about this, you can always contact our team!
