Question

I’m consuming a web service that returns an array of objects called $viewData like so:

Array
(
    [0] => stdClass Object
        (
            [id] => 64757
            [title] => Frogger
            [votes] => 1
            [status] => gotit
        )

    [1] => stdClass Object
        (
            [id] => 64758
            [title] => The Legend of Zelda
            [votes] => 1
            [status] => wantit
        )

    [2] => stdClass Object
        (
            [id] => 64759
            [title] => Grand Theft Auto
            [votes] => 1
            [status] => wantit
        )

)

I need to split this into two separate arrays – one that contains all the objects whose status is wantit, and the other whose status is gotit.

I can get one array out of it by using array_filter() with a custom function:

if(is_array($viewData) and (!empty($viewData))) {
    function splitGames($v){
        if ($v->status==="gotit") {
          return true;
        }
        return false;
    }

    $gotEm = array_filter($viewData, "splitGames");
    print_r($gotEm);

}

This function returns what I’d expect:

Array
(
    [0] => stdClass Object
        (
            [id] => 64757
            [title] => Frogger
            [votes] => 1
            [status] => gotit
        )
)

Is there a way to automatically get what’s left of the original array into a second array, or do I need to have a second custom function that looks for a status of “wantit” and rerun array_filter() again on the original array?

Answer 1

If you need two arrays, you will need to call array_filter twice.

Alternatively, you could start with two empty arrays and just loop once over $viewData, placing each array member into one of the two arrays based upon the status value.

Does that help?
