PhpStorm Field accessed via magic method

Question

I have ignited datatables Library in my CodeIgniter library folder.

Some Code from Library

class Datatables
{
    /**
     * Global container variables for         


        

Answer 1

As mentioned by LazyOne in the question comments:

You have to declare them via @property in PHPDoc comment that belongs to that class.

/**
 * @property string $bar
 */
class Foo {

    public function __get($name) {
        if ($name == 'bar') {
            return 'bar';
        }
        return NULL;
    }
}
