我想访问其父级为“Shipping”的子数组'minicomp'中每个对象的base_id。我该如何访问它?
答案 0 :(得分:1)
首先使用json_decode()
将json转换为数组。就像这样..
$json =<your json>;
$array = json_decode($json,true);
Then
echo $array['Shpping '][0]]['minicomp'][0]['id'];//outputs 1
示例:
<?php
$json = '[{
"id": "1",
"name": "Dress",
"deleted_at": null,
"created_at": null,
"updated_at": null,
"minicomp": [{
"id": "1",
"cname": "basic",
"base_id": 44
}, {
"id": "2",
"cname": "Shirt",
"base_id": 177444
}, {
"id": "3",
"cname": "Pants",
"base_id": 444
}]
}]';
$array = json_decode($json,true);
//print_r($array);
$minicomp = $array[0]['minicomp'];
echo $minicomp[0]['id'];
echo $minicomp[1]['id'];
?>
更新
获取所有ID。没有定义索引。使用foreach循环:
foreach($minicomp as $key=>$value){
echo $minicomp[$key]['id']."<br/>";
}
