PHP decode nested JSON
提问by ptamzz
I've a nested JSON code as (it's actually my facebook status updates)
我有一个嵌套的 JSON 代码（它实际上是我的 facebook 状态更新）
{
"data": [
{
"id": "1290561400000000",
"from": {
"name": "My name",
"id": "500920000"
},
"message": "Message body",
"updated_time": "2010-08-24T08:22:13+0000",
"comments": {
"data": [
{
"id": "129056140474641_8000",
"from": {
"name": "name1",
"id": "100000486072000"
},
"message": "hahahahahahha..........",
"created_time": "2010-08-24T08:40:39+0000"
},
{
"id": "129056140474641_8000000",
"from": {
"name": "name2",
"id": "1597542457"
},
"message": "true ya. I have updated",
"created_time": "2010-08-24T08:59:53+0000"
},
{
"id": "129056140474641_83000",
"from": {
"name": "Name3",
"id": "1000004860700000"
},
"message": "am putting it on my wall....",
"created_time": "2010-08-24T09:01:25+0000"
}
],
}
}
]
Now how do I access the comments for a particular update and print it through a loop?? (I'm retrieving say a couple of updates at the same time).
现在如何访问特定更新的评论并通过循环打印？（我正在检索同时说几个更新）。

Use json_decode():
$decoded = json_decode($json_string);
$comments = $decoded->data[0]->comments->data;
foreach($comments as $comment){
$name = $comment->from->name;
$message = $comment->message;
//do something with it
}

You can use the json_decodefunction to convert it to array and then iterate over the array using foreachloop.
您可以使用该json_decode函数将其转换为数组，然后使用foreach循环遍历数组。
$array = json_decode($json, true);
foreach($array as $key => $value)
{
// your code....
}
The second option to json_decodeis whether or not you want to convert it to an array.
第二个选项json_decode是您是否要将其转换为数组。
