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, a class is defined using the class keyword, followed by the name of the class 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.
