OOP. How to implement to the same classes

phpOops

This is class of a car.

<?php
class Desc { // file or folder
var $name;
var $size;
var $link;
function SetName($name) {
    $this->name = $name;
}
function GetName() {
    return $this->name;
}
}

I want to use up a lot of these classes (many of the same car).
Please help me :-(

p.s.: hello from Russia :-)

Well, it does not sound like the Desc class models a car at all. But if you did want to instantiate objects of this class, you would write:

$x = new Desc();

I suspect we may need a better explanation of what you mean by "use up a lot of these classes". Perhaps something was lost in the translation from Russian to English? 🙂

Now i have one car (one class).
I want many cars.

How i can i make it in OOP.

p.s.: translated to English with translate.google.com :-((

Perhaps an object that can store a collection of car objects? You can make use of PHP 5's object iterators, too:

<?php
class Car
{
   public $name;
   public $size;
   public $link;
   public function __construct($name, $size='', $link='')
   {
      $this->name = $name;
      $this->size = $size;
      $this->link = $link;
   }
}

class CarCollection implements Iterator
{
   private $collection = array();

   /**
    * Add Car object to collection
    * @return bool
    * @param object $car
    */
   public function addCar(Car $car)
   {
      $this->collection[] = $car;
      return true;
   }

   /* methods to implement Iterator: */
   public function rewind()
   {
      reset($this->collection);
   }
   public function current()
   {
      return current($this->collection);
   }
   public function key()
   {
      return key($this->collection);
   }
   public function next()
   {
      return next($this->collection);
   }
   public function valid()
   {
      return $this->current() !== false;
   }
}

// Example usage:

$carLot = new CarCollection();
// add some test data:
foreach(range(1,9) as $num)
{
   $carLot->addCar(new Car("Name $num", "size $num", "link $num"));
}
// use the object iterators to view data:
echo "<ul>\n";
foreach($carLot as $k1 => $car)
{
   echo "<li>$k1:\n<ul>\n";
   foreach($car as $key => $value)
   {
      echo "<li>$key: '$value'</li>\n";
   }
   echo "</ul>\n</li>\n";
}
echo "</ul>";

Thanks to All...

NogDog, your code is beautiful code :-)
I'll use your code.
