打印嵌套数组php的值

Question

首先让我说，我已经通过了很多相关的问题在这里，但没有一个解决我的问题。我有和php嵌套数组在db和需要打印所有的值。输出输出第一个最顶层数组(它是'name'，值为"Office, home")，但没有得到'BB"中包含的嵌套数组值。这是我的代码:

function getTB($name='', $value='') {
$value    = json_decode($value);
$name = '';  $BB= ''; 
foreach ($value  as $key=>$val) {
    $name .= $val['name'].',';

JSON代码:

[{"name":"Office","TB":[{"date":[false,true],"time":"8:00 AM"}]},{{"days":[false,true],"time":"6:00 PM"},

Answer 1

use array_walk_recursive

例如

如果你有这样的json(它有一个子数组)

$decoded = json_decode('{"abc": "one",
                         "def": "two",
                         "sub_array": {
                                 "ABC": "ONE"
                                 }}', true);
array_walk_recursive($decoded, function($value,$key) {
  echo $key.' :'.$value.'<br>';
});

输出将是

abc :one
def :two
ABC :ONE

所以像这样使用而不是普通的foreach

更新

像这样使用

$arr='[{"name":"Office","TB":[{"date":[false,true],"time":"8:00 AM"},{"days":[false,true],"time":"6:00 PM"}]}]';
$rr=json_decode($arr);
foreach ($rr[0]->TB as $key => $value) {
array_walk_recursive($value, function($k,$kk){
     echo 'Key is '.$kk.' & Value is '.$k.'<br>';   
});
}

输出:

Key is 0 & Value is 
Key is 1 & Value is 1
Key is time & Value is 8:00 AM
Key is 0 & Value is 
Key is 1 & Value is 1
Key is time & Value is 6:00 PM
