php - 我如何在php中获取json

我从json获得了一个数组，但我不知道如何获取booktitle和url。
如何读取数组中的这些项？

$data = file_get_contents('C:\Users\rsanchro\Desktop\ftp brasil4-9-2015\moderna_plus-historia\MPCH-C05-P1-1.0.1-ZIP-PT\resource.json');
$datos = json_decode($data, true);

print_r($datos);die;

Results:
    Array
    (
        [topBarColor] => #000000
        [bookId] => 2aef55bf3a9dec377b4f16a8048c7f84
        [bookTitle] => HistÃ³ria
        [unitId] => MPCH-C05-P1
        [unitTitle] => 108-127-MPCH-C05-P1-M
        [unitResources] => Array
            (
                [0] => Array
                    (
                        [type] => 03
                        [url] => resources/mphis_c06av_escultura_ontem.mp4
                        [urlToShowInsideUnit] => #/compId/id0a33b2a0471e0f444bc0a88b5bb55714
                        [title] => A escultura ontem e hoje
                        [page] => 123
                    )

            )

    )

最佳答案

用这个

        print_r(utf8_decode($datos['bookTitle']));
        if(is_array($datos['unitResources']) && count($datos['unitResources']) > 0){
            foreach($datos['unitResources'] as $key => $value){
                print_r($value['url']);

            }
        }
