When I first started learning programming, the concept of Object-Oriented Programming (OOP) seemed a bit confusing. But once I began using it in PHP and C++, things started to make sense. OOP is a programming paradigm that organizes code around objects and classes. It made my code cleaner, easier to manage, and more like how we think in real life.
In both PHP and C++, the main fundamentals of OOP are the same: encapsulation, inheritance, polymorphism, and abstraction.
Let me explain each using a simple example. When I built my first mini project—a "Student Management System"—I created a class called Student. In PHP, it looked something like this:
class Student {
public $name;
public $grade;
public function __construct($name, $grade) {
$this->name = $name;
$this->grade = $grade;
}
public function getDetails() {
return "$this->name is in grade $this->grade.";
}
}
In C++, it was quite similar:
class Student {
public:
string name;
int grade;
Student(string n, int g) {
name = n;
grade = g;
}
string getDetails() {
return name + " is in grade " + to_string(grade) + ".";
}
};
This means bundling data and methods that operate on that data within one unit—a class. It helps protect internal data from unwanted access. I used private variables and public methods to control access.
I created a new class GraduateStudent that inherited from Student. It allowed me to reuse code and only add what was unique to graduate students.
I used method overriding in PHP and C++ to allow GraduateStudent to have a different version of getDetails(). This gave me flexibility and made my code adaptable.
This helped me hide complex logic from users. For example, I could write a method that calculates GPA internally and only return the final result.
Using OOP in both PHP and C++ made my projects more modular and scalable. Once I learned how to break things into objects, programming felt more natural. Whether you're building websites with PHP or performance-heavy software with C++, understanding OOP is a powerful skill that opens many doors.

Encapsulation​
This means bundling data and methods that operate on that data within one unit—a class. It helps protect internal data from unwanted access. I used private variables and public methods to control access.
Inheritance​

Polymorphism​
I used method overriding in PHP and C++ to allow GraduateStudent to have a different version of getDetails(). This gave me flexibility and made my code adaptable.
