| ``length`` |
| ========== |
| |
| The ``length`` filter returns the number of items of a sequence or mapping, or |
| the length of a string. |
| |
| For objects that implement the ``Countable`` interface, ``length`` will use the |
| return value of the ``count()`` method. |
| |
| For objects that implement the ``__toString()`` magic method (and not ``Countable``), |
| it will return the length of the string provided by that method. |
| |
| For objects that implement the ``Traversable`` interface, ``length`` will use the return value of the ``iterator_count()`` method. |
