数组作为函数参数

Question

I'm currently recoding some code. It's from project I'm running at the moment.

class store extends TModel{
    public function render_cart( $a=0, $b=0, $c=0 ){
        echo '<pre>'; var_dump( $a=0, $b=0, $c=0 ); echo '</pre>';
    }
}

class TController extends TObject{
    function getModel($model=''){
        include( TPATH_COMPONENT.'models'.DS.$model.'.php' );
        $this->_model = new $model;
        return false;
    }
    function get($method=''){
        $args = func_get_args();

        return $this->model->$method( $args );
    }
}

$controller->getModel('store');        
$cart = $controller->get('render_cart', 1, 2, 3 );

I want transfer args from TController::get to store::render_cart( $a=0, $b=0, $c=0 ) as it's arguments. Thanks for your help.

You would need to write the method like this:

function get($method=''){
    $args = func_get_args();
    $method = array_shift($args);
    return call_user_func_array([$this->model, $method], $args);
}

After getting the method name and arguments into $args, use array_shift to isolate the method name from the arguments.

To pass the arguments (whose number is unknown) to the model's method you need to use call_user_func_array. You already have the arguments array for this call, but you still need the callable. That one is created on the spot as an array of two items per the documentation.
