PHP - Extracting a property from an array of objects

Question

I\'ve got an array of cats objects:

$cats = Array
    (
        [0] => stdClass Object
            (
                [id] => 15
            ),
                 


        

Answer 1

You can do it easily with ouzo goodies

$result = array_map(Functions::extract()->id, $arr);

or with Arrays (from ouzo goodies)

$result = Arrays::map($arr, Functions::extract()->id);

Check out: http://ouzo.readthedocs.org/en/latest/utils/functions.html#extract
