Question

Twig lets you pass array or object to the template and gives you the same interface to access members for both data structures.
So, for example:

$test = array('foo' => 'foo', 'bar' => 'bar');

Will let you access this in template as test.foo and test.bar

Now instance of this object will have the same effect. Which is very awesome 🙂

class test
{
    public $foo;
    public $bar;
}

How about an object that uses magic __set and __get methods?

class test
{
    public $properties;

    public function __set($name, $value)
    {
        $this->properties[$name] = $value;
    }

    public function __get($name)
    {
        return $this->properties[$name];
    }
}

Unfortunately in this case you can’t access properties of this object.
I’m not sure if the Twig is the issue here or PHP itself.

You need to implement __isset() as well, eg

public function __isset($name) {
    return array_key_exists($name, $this->properties);
}
