Arrays and objects

bobr3940

Can you make an array of objects?

Class car {
     Public $color;
     Public $model;
     public $cost;
}

$mycar = new car;

$mycar[1]->color = "blue";

or do I have to do the following:

Class car {
     Public $color;
     Public $model;
     public $cost;
}

$mycar = new car;

$mycar->color[1] = "blue";

Thank you for looking.

Not sure if this is what you want, but yes, you could have an array of objects.

<?php
class Car
{
   public $color;
   public $model;
   public $cost;
}
$mycar = array();
$mycar[1] = new Car();
$mycar[2] = new Car();
$mycar[1]->color = 'blue';
$mycar[2]->color = 'red';

echo "<pre>".print_r($mycar, true)."</pre>";

There is even something called:
ArrayObject
in PHP.

It is an object that you can use in some cases as an array.
We can say it is not a true array and neither a true object.
It has got features from both and is something in between.

Example:
foreach($array AS $x)
will not work to loop an object. You get error.

But if you use an ArrayObject with indexes like $ArrayObject->a0, ArrayObject->a2, ArrayObject->a3, values,
foreach will work just as if you are looping an array:
foreach($ArrayObject AS $a)

Here is PHP ArrayObject Class & Functions:
