I always write them like so: 
my_function_call(
    $arg1,
    $arg2,
    $arg3,
);

I indent all blocks, whether they be code, anonymous array/hash constructors, parameter (or other) lists, or anything else in the same way. Makes a lot of sense, if you ask me, when you're nesting calls: 
my_function_call(
    my_other_function_call(
        $arg1,
        $arg2,
        and_yet_one_more_function_call(
            $arg1,
            $arg2,
            $arg3,
        ),
    ),
    $arg2,
    $arg3,
);

                                        $arg2,

+(
                                                                      
+ $arg1,
