Example

Take for example this array :

$baseArray = array(
 'director' => array(
 'first_name' => 'Robert',
 'last_name' => 'Zemeckis',
 ),
 'actors' => array(
 array(
 'first_name' => 'Michael J.',
 'last_name' => 'Fox',
 ),
 array(
 'first_name' => 'Christopher',
 'last_name' => 'Lloyd',
 ),
 ),
 'label' => 'Back to the Future'
);

If we filter it like this :

use agallou\ArrayFilterPath\ArrayFilterPath as ArrayFilterPath;
$filter = new ArrayFilterPath();
$filters = array(
 'actors[].last_name',
 'label',
);
$filteredArray = $filter->filter($baseArray, $filters);

We will get an array like this, with only the actors last name and the label :

array(
 'actors' => array(
 array(
 'last_name' => 'Fox',
 ),
 array(
 'last_name' => 'Lloyd',
 ),
 ),
 'label' => 'Back to the Future'
);
