Nested classes

[Anon]

here is my problem:

I have a class that contains an instance of another class (nested not extended!!!)

Something like:

class a{
var $name;
function setName($strName){
$this->name = $strName;
}

class b{
var $obja;
var $b;

function b(){    /* constructor */
    $obja = new a;
}

function setNameA(str){
    $this->obja->setName(str);    /* this line give me an error: */
}                                                       /* Call to a member function on a non-object */

I tried also:

function setNameA(str){
    $tmp = $this->obja;
    $tmp->setName(str);
}

that produces the same error (this is like your example (I think))

also tried
function setNameA(str){
global $obja;
$obja->setName;
}
getting the same error...

Any ideas???

Answer if you can.

Thanks for your time
