PHP - best way to initialize an object with a large number of parameters and default values

Question

I\'m designing a class that defines a highly complex object with a ton (50+) of mostly optional parameters, many of which would have defaults (eg: $type = \'foo\'; $width

Answer 1

Just to follow up with how I implemented this, based on one of Daff's solutions:

    function __construct($args = array()){
        // build all args into their corresponding class properties
        foreach($args as $key => $val) {                
            // only accept keys that have explicitly been defined as class member variables
            if(property_exists($this, $key)) {
                $this->{$key} = $val;
            }
        }
    }

Improvement suggestions welcomed!
