}

print_r(

Output:

Array
( [0] => a
[1] => b
) Array
( [Ccontainer] => Array
(
[0] => a
[1] => b
)

)

Because the result is not the same?

An object is not the same as a basic type. A basic type holds one or
more values. An object can also have methods to operate on those
values. The two are not compatible.

The object can be of any type, so the whole depends on the class definition.

for example:
class myclass {
public $array = Array();
public function getFirst() {
if(sizeof($this->array) == 0)
{
return null;
}
return $this->array[1];
}
}

this has the method getFirst.

It means that the ArrayObject is a built-in type allows an object to
function as an array, as the PHP doc says. Your user-defined object
contains an array but does not function as an array, as the output from
print_r() shows.

So there is no way to create an object (class) that can *also* function
as an array?

- A class can have an variable that is an array.
- An array can hold objects.

You can make objects to have links to other objects (reference), then it
would be a bit array like at the same time it can hold it's data, the
problem will be that none of the array functions in PHP will work, so I
think you need to pick one of the two options that have to use real arrays.

<?php
$a = new Object();

// $b is a new reference ("link") to the object in $a and not(!) a copy

$b = $a;

// Now we change something in the object

$b->setName('foobar');

// This will return the same name wich was just set using $b since
// $b is just another reference to the object originally assinged to $a

$a->getName();
?>

If you need a copy of an object, you need to use the "clone" keyword:

<?php
$a = new Object();

// This will create a copy of the object in $b
$b = clone $a;
?>
