首先让我说我在这里经历了很多相关的问题,但没有一个能解决我的问题。我有和db嵌套数组在db中,需要打印所有的值。输出打印出第一个最顶层的数组('名称'和值" Office,home")但没有得到包含在&#39中的嵌套数组值; BB&#34 ;. 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"},

答案 0 :(得分:1)

使用array_walk_recursive

例如,如果你有像这样的json(有一个子阵列)

$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

<强> 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>';   
});
}

<强> 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
