var_dump($propertyAccessor->getValue($persons, '[0][first_name]')); // 'Wouter'
var_dump($propertyAccessor->getValue($persons, '[1][first_name]')); // 'Ryan'

.. tip::

If the key of the array contains a dot ``.`` or a left squared bracket ``[``,
it is possible to escape these characters with a backslash. In the above example,
if the array key ``first_name`` becomes ``first.name``, accessing the value can
be achieved like this::

var_dump($propertyAccessor->getValue($persons, '[0][first\.name]')); // 'Wouter'
var_dump($propertyAccessor->getValue($persons, '[1][first\.name]')); // 'Ryan'

Right squared brackets ``]`` don't need to be escaped.

.. versionadded:: 6.3

Escaping dots and left squared bracket in a property path was
introduced in Symfony 6.3.
