[Resolved] Returning nunll from a class

[Catharsis]

Hi there.

I was wanting to do a similar thing that I do in perl ion php. I'll explain. What I want to do is call a class with a single parameter, if that parameter is not one of the few that I am expecting I effectively want to log an error and return 0 or undef.

So my class looks a little like this..

class My_Type
{    

    var $value;
    var $type;

var $logger;

function My_Type ($type)
{

    switch ($type) {
    case 'foo':
        $this->type = 'foo';
        $this->value = 1;
        break;
    case 'bar':
        $this->type = 'bar';
        $this->value = 2;
        break;
    default:
        // I dont recognise this type.. return 0?
        return 0;
    }

}
}

And in my main code, something like

$type = new My_Type('wibble');
print get_class($type);

Now no matter if I return 0 or not it still returns the class. Is there an easy way to test to see if the class call worked?

in PHP4:

$this = 0;

in PHP5: throw an exception

Simple, yet incredibly effective, thank you!
