Inheritence In PHP

One of the main advantages of object-oriented programming is the ability to reduce code duplication with inheritance. Code duplication occurs when a programmer writes the same code more than once, a problem that inheritance strives to solve. In inheritance, we have a parent class with its own methods and properties, and a child class (or classes) that can use the code from the parent. By using inheritance, we can create a reusable piece of code that we write only once in the parent class, and use again as much as we need in the child classes.

class Parent {
  // The parent’s class code
}
 
class Child extends Parent {
  // The  child can use the parent's class code
}
