PHP – Classes – Objects

PHP – Classes – Objects

La classe è un contenitore per variabili e funzioni, ad esempio ‘class Car’ contiene variabili e funzioni, è un buon modo per raggruppare cose che funzionano insieme.

An object is a data type which stores data and information on how to process that data.

In PHP, an object must be explicitly declared.

First we must declare a class of object. For this, we use the class keyword. A class is a structure that can contain properties and methods.

We then define the data type in the object class, and then we use the data type in instances of that class.

<?php
class Car // first you HAVE TO declare the object
{
  var $color;
  function Car($color="green") 
  {
    $this->color = $color;
  }
  function what_color() 
  {
    return $this->color;
  }
}
?>
