I've got an array of cats objects:

$cats = Array
    (
        [0] => stdClass Object
            (
                [id] => 15
            ),
        [1] => stdClass Object
            (
                [id] => 18
            ),
        [2] => stdClass Object
            (
                [id] => 23
            )
)

and I want to extract an array of cats' IDs in 1 line (not a function nor a loop).

I was thinking about using array_walk with create_function but I don't know how to do it.

Any idea?

If you have PHP 5.5 or later, the best way is to use the built in function array_column():

$idCats = array_column($cats, 'id');

But the son has to be an array or converted to an array

You should point to your vendor/autoload.php at Settings | PHP | PHPUnit when using PHPUnit via Composer.

This blog post has all the details (with pictures) to successfully configure IDE for such scenario: http://confluence.jetbrains.com/display/PhpStorm/PHPUnit+Installation+via+Composer+in+PhpStorm

P.S. The WI-18388 ticket is already fixed in v8.0

On Mac OS X environment variables available in Terminal and for the normal applications can be different, check the related question for the solution how to make them similar.

Note that this solution will not work on Mountain Lion (10.8).

You either iterate the array, searching for the particular record (ok in a one time only search) or build a hashmap using another associative array.

For the former, something like this

$item = null;
foreach($array as $struct) {
    if ($v == $struct->ID) {
        $item = $struct;
        break;
    }
}

See this question and subsequent answers for more information on the latter - Reference PHP array by multiple indexes

You can use the forEach method to execute a provided function once for each element in the array. In this provided function you can add the Active property to the element.

Results.forEach(function (element) {
  element.Active = "false";
});
