OO question about object array

[Anon]

I have a series of simple classes, with a hierarcical structure.

The first (TCell) encapsulates a couple of simple variables, and has a method called toString (a-la-java).

The second (TRow) encapsulates a couple simple vars and an array (called cell) of TCell Objects.
It also has a toString method.

My problem is that I want to call the TCell's toString method inside the TRow's toString method and iterate over the array of TCells.

like:

$out;
foreach(list($k, $v) = each($this->cell))
{
$out .= $this->cell[$k]->toString();
^ ^
|-------------------------|
this is the problem,
}

Thanks

So what is the problem you are having? Provided that "cell" has the proper object references, the code snipet you posted should work. What are the errors you are observing?

Thank you, but I managed to figure that the default constructor was creating the var cell with an initial value that was not an object (a string actually), and so when iterating through the array like in the previous code, which called the TCell toString function on the that first value the parser was thowing an error,

Call to a member function on a non-object
