hi there

 

im am making a php validation class with sub classes that extend it, eg, mobile, suburb, credit_card, ect

 

so, the idea is you can call

 

$validation = new Validation('mobile');
$valid = $validation->validate($number);

$validation->type('suburb');
$valid2 = $validation->validate($suburb);

now my idea for doing this is having

 

class Validation {
    private $v_type = null;

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

    public function type($type) {
        $this->v_type = new $type();
    }

    public function validate($info) {
        return $this->v_type->validate($info);
    }
}

as a very basic example

 

but is there a better way of doing this?

Why not just

$validation = new Suburb();
$valid2 = $validation->validate($suburb);

 

?
