我确实一直在努力正确地输出我从rest API响应接收到的json数据的内容。我已经搜索了很多并尝试了不同的方法，但是我注意到每个人的始终都是唯一的...下面是我的代码。特别是考虑到的是“ headers_field”，它是一个包含许多值和键的数组...我想要也可以通过键输出这些值...虽然（“ data”）带有两个值...下面也是我尝试过的方法，但是我只是从循环中返回（“ headers_field “：Array），（” box：Array“）..我使用了Curl。请看下面。谢谢。

只要您知道从API返回的数组有多深或有多少维，并且知道密钥结构将是相同的，就可以使用如下代码：
[注意：我拿走了您的JSON，并快速又肮脏地吐出了所有键和值-包括嵌套的标头字段。本质上是基于值是否为ARRAY的。如果您知道期望的结构，则可以通过创建一个数组映射和一个函数来处理所有属于子数组的val来使它更加优雅。
无论如何-希望以下内容对您有所帮助：
foreach($theDecodedData['data']["header_fields"] as $row){
foreach($row as $key => $val){
if(!is_array($val)){
echo "$key: $val \n";
}
else{
echo "Contents of $key \n";
foreach($val as $vkey => $vval){
if(!is_array($vval)){
echo "$vkey: $vval \n";
}
else{
echo "Contents of $vkey \n";
foreach($vval as $vvvkey => $vvvval){
if(!is_array($vvvval)){
echo "$vvvkey: $vvvval \n";
}
else{
echo "Contents of $vvvkey \n";
foreach($vvvval as $vvvvkey => $vvvvval){
echo "$vvvvkey: $vvvvval \n";
}
}
}
}
}
}
}
}
