JSON的foreach只得到第一个结果出来一个数组

Question

我有一个JSON文件（test.json），这是

{ 
    "fruit": [{ 
     "id": 364823, 
     "name": "Lemon", 
     "amount": [33], 
     "profile": "http://google.com", 
     "buyid": 5 
    }, { 
     "id": 367851, 
     "name": "Orange", 
     "amount": [69, 95, 166], 
     "profile": "http://google.com", 
     "buyid": 3 
    },{ 
     "id": 35647, 
     "name": "Apple", 
     "amount": [77, 43], 
     "profile": "http://google.com", 
     "buyid": 31 
    } ] 
} 

那么我有我的PHP脚本来呼应

$url="test.json"; 
    $json = file_get_contents($url); 
    $json = json_decode($json, true); 
    $names = array(); 
    foreach($json['fruit'][0]['amount'] as $val) 
{ 
    echo $val . " <br> "; 
} 

它返回

33 

我怎样才能得到它返回？

33 
69 95 166 
77 43 

我可以得到它与其他工作一样ID，轮廓和buyid但不是这个数组

Answer 1

foreach($json['fruit'] as $fruit){ 
    echo implode(' ',$fruit['amount']); 
}
