PHP stdClass & objects foreach

Question

So I have some code looking like this at the moment:

    $filter = new \stdClass();

    $queryObj = $this->getpost['filter'];

    $filters = new \stdClass();
    $filters->team = $queryObj['team'];
    $filters->skill = $queryObj['skill'];
    $filters->division = $queryObj['division'];

    $filter->filters = $filters;
    $users = $managerStatistics->getManagerDeliveryData($filter);

I fellt the need to do this because in the getManagerDeliveryData(§filter), there is a "foreach $filter->filters"..

Does anyone know how to do this in a better looking way? This looks messy to me but I'm not sure what to do here..

What exactly looks messy to you here?

You could rewrite the way you build the data into a more compact format, casting each array definition to an object as needed...

$filter = (object) [
        "filters" => (object) [ 'team' => $queryObj['team'], 
                'skill' => $queryObj['skill'], 
                'division' => $queryObj['division'] ]
];

This is what I'm talking about, wonder when these things will start coming naturally :(

If you cast an associative array to an object, it becomes a stdClass object with matching properties. Here's a generic example:

$arr = ['one' => 'foo', 'two' => 'bar', 'three' => 'meh']; 
$obj = (object) $arr;   

var_dump($obj);

This would give you:

object(stdClass)#2 (3) {
    ["one"] · string(3) "foo"
    ["two"] · string(3) "bar"
    ["three"] · string(3) "meh"
}

In your case, you could do the following, if you're hoping to not have to name your $queryObj keys/values one by one (which is necessary if e.g. the filter list isn't fixed, and therefore can't be hard-coded):

$filters = (object) $queryObj;

Obviously, every key/value pair in the source array then becomes a property/value pair in the object. If there are particular values you want to omit, either unset them or use array_intersect_key() etc. functions to only cast the desired keys. Suppose your $queryObject had a bunch of keys, but you only wanted the ones in your example, you could do this:

$keymap = ['team', 'skill', 'division'];
$filters = (object) array_intersect_key(array_flip($keymap), $queryObject);
