I have the following code block after formatted:
class A extends B
{
    protected $arr  = ['a'    => 1,
        'aa'   => 2,
        'aaa'  => 3,
        'aaaa' => 4,];
    protected $arr1 = ['a' => ["apple",
            "banana",
            "orange",
            "watermelon",],
        'b' => ['b',],];

}


in PHPStorm it will becomes

class A extends B
{
    protected $arr  = ['a'    => 1,
                       'aa'   => 2,
                       'aaa'  => 3,
                       'aaaa' => 4,];
    protected $arr1 = ['a' => ["apple",
                                "banana",
                                "orange",
                                "watermelon",],
                       'b' => ['b',],];

}


It looks much more smarter.
