Oops concepts in php

The  PHP Object-Oriented Programming concepts are:
Class 
Objects
Inheritance
Interface
Abstraction
Magic Methods

Classes are nothing without objects! We can create multiple objects from a class. Each object has all the properties and methods defined in the class, but they will have different property values. Objects of a class is created using the new keyword. PHP OOP - Classes and Objects OOP Case. Let's assume we have a class named Fruit. A Fruit can have properties like name, color, weight, etc. Define a Class. A class is defined by using the class keyword, followed by the name of the class and a pair of curly Define Objects. Classes are nothing

Php object

$o= new \stdClass();
$o->a = 'new object';

OR

$o = (object) ['a' => 'new object'];

A class may contain its own constants, variables (called "properties"), and functions (called "methods"). Example #1 Simple Class definition.

Class php

{$foo->{getVarName()}}();

Classes are the blueprints of objects. One of the big differences between functions and classes is that a class contains both data (variables) and functions that form a package called an: 'object'. Class is a programmer-defined data type, which includes local methods and local variables. The Basics class. Basic class definitions begin with the keyword class, followed by a class name, followed by a pair of curly new. To create an instance of a class, the new keyword must be used. An object will always be created unless the object Properties and methods. Class properties and

Create a class in php

name = $name;
    $this->color = $color;
  }
  function get_name() {
    return $this->name;
  }
  function get_color() {
    return $this->color;
  }
}

$apple = new Fruit("Apple", "red");
echo $apple->get_name();
echo "
"; echo $apple->get_color(); ?>

Object Oriented Concepts · Class − This is a programmer-defined data type, which includes local functions as well as local data. · Object − An individual instance  Class is a programmer-defined data type, which includes local methods and local variables. Class is a collection of objects. Object has properties and behavior. Syntax: We define our own class by starting with the keyword ‘class’ followed by the name you want to give your new class.

Php define class

class Bike {
    	function Bike() {
            $this->type = 'BMX';
    }
}

$blackSheep = new Bike();

print $blackSheep->type;

Key Concepts. Review core concepts you need to learn to master this subject. PHP extends keyword. PHP Constructor Method. PHP class  Following are some of the key aspects of a PHP class: Define a class with keyword “class” followed by name of the class Define the constructor method using “__construct” followed by arguments. The

How to declare a method?

Let's declare a method inside a class named Example class to echo out a simple string that we give.


We use the public keyword to make the method available inside and outside the class. You will learn more about this in the visibility chapter.

How to call a method?


$example = new Example();
$example -> echo('Hello World');

Result: Hello World

Explained:
  • First, we create an object ($example) from the class Example
  • Next, we call the method echo with -> (object operator) and () (parentheses)
  • The parentheses contain the arguments as usual

The thing you need to understand is that we call methods on objects, not classes.
