Assigning to $this in PHP 5

raygr

I'm porting some code from PHP 4 to PHP 5. It's not liking this:

$s = _SESSION['x'];
$this = unserialize($s); // error: can't assign to $this

The reason I'm doing this is to have a class method called "LoadFromSession". If you have a better way to do this, please tell me.

My basic question is this:

In PHP 5, I would like to be able to copy over the contents of the current object. Is there a way to assign a new object to the current object (pointed to by $this)? For eg:

$this = $otherobject_of_same_type;

It this were C++, I would do this:

*this = object;

Thanks.

Use Object cloning.

Object cloning doesn't quite do what I need because I can't do this:

$this = clone object;

That's true; you can't do that (why I suggested cloning).

Maybe this comes close enough:

class CloneMe 
{ 
    public $string = ''; 

function __construct($str) 
{ 
    $this->string = $str; 
} 

function clone_this($obj) 
{
    return $obj;
}
} 

$obj_x = new CloneMe('obj_x');
$obj_1 = new CloneMe('obj_1');
$obj_1 = $obj_1->clone_this($obj_x);
