``length``
|
|
==========

|
.. versionadded:: 2.3
|
|
|
|
Support for the ``__toString()`` magic method has been added in Twig 2.3.
|
|
|
|
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 ``IteratorAggregate`` interface, ``length`` will use the return value of the ``iterator_count()`` method.
