If I understood correctly what you mean, it is possible. I did something
like this once. I wanted to instantiate an object of a class which had an
arbitary number of columns. It was sort of a table container. All columns
had a certain length and I create the structure of the table in the
constructor... So to create a table with two columns, one 20 units wide and
another 40 units wide, I'd call the constructor $myTable = new table(20,40);
or just as well new table(100,20,30,5,12,40);
Here's the definition of the constructor:

public function __construct(){
if(func_num_args()){
foreach(func_get_args() as $arg){
$this->columns[] = $arg;
}
}
}

So as you see, the constructor has no parameters at all, I just catch all
that were passed to it with the func_get_args() function that returns a list
of all the parameters passed to the method, and walk it thru. All very
simple. Is this what you mean?
