如何使用PHP在嵌套的JSON数组中查找值

Question

我试图使用PHP在嵌套的JSON中查找值。我已完成了print_r()并得到：

Array
(
    [types] => Array
        (
            [0] => Array
                (
                    [name] => Running
                    [arabicName] => الجاري
                    [categories] => Array
                        (
                            [0] => Array
                                (
                                    [name] => Entertainment
                                    [arabicName] => تسلية
                                    [programs] => Array
                                        (
                                            [0] => Array
                                                (
                                                    [id] => 375
                                                    [name] => Saalo Marteh
                                                    [arabicName] => 
                                                    [image] => http://plus.mtv.com.lb/Chrome/KPanel/Pictures/Programs/151120100928327.jpg
                                                )

                                            [1] => Array
                                                (
                                                    [id] => 491
                                                    [name] => Celebrity Duets
                                                    [arabicName] => 
                                                    [image] => http://plus.mtv.com.lb/Chrome/KPanel/Pictures/Programs/151108084429774.jpg
                                                )

我试图在娱乐标题下获取name和id的值。 我尝试过以下但没有运气：

echo $json['types']['categories'][0]['name'];

Answer 1

foreach ($json['types'][0]['categories'][0]['programs'] as $value) {
    echo $value['id'] . ' ' . $value['name'];
}
