Classes

Classes are the blueprint of objects. Classes hold their own data members and member functions, which can be accessed and used by creating an instance of that class. In PHP class is defined using the class keyword, followed by the name of classes and curly braces ({}). 

Example:

 

<?php
class class_name {
  // code goes here...
}
?>

 

Creating a Class in PHP

We will create a class Employee where we will have two properties and two methods for setting and getting the property.

<?php
class Employee {
  // Properties
  public $name;
  public $surname;

  // Methods
  function set_name($name) {
    $this->name = $name;
  }
  function get_name() {
    return $this->name;
  }
}
?>

Note: The $this keyword refers to the current object, and is only available inside methods.
