Handle Null Argument

[TomTees]

How do I make my constructor work when I don't pass in an argument.  That is, it should efault to null.

 

	class Something{
	private $type=null;

	public function __construct($t){
		$this->type = $t;
	}

	public function setSomething($t){
		$this->type = $t;
	}

	public function getSomething(){
		if (is_null($this->type)) {
			return "None for you!";
		} else {
			return "Something is " . $this->type . ".";
		}
	}
}

If you're looking to make it more advanced you can achieve constructor overloading with PHP using func_get_args() and func_num_args(). Unfortunately it's not natively implemented.

I thought I tried that earlier, but it didn't work.  Oh well.

 

Thanks!!!!
