Question

我有这个数组，我想从中获取ID和描述。我得到的只是阵列阵列......： - ）

function getCountries() {
$json = file_get_contents('http://onleague.stormrise.pt:8031/OnLeagueRest/resources/onleague/Utils/Countries');
$data = json_decode($json, TRUE);
$countries = array(); 
foreach($data['data']['item'] as $item) {
    $countries[] = $item;
}
//print_r($countries);
foreach($countries as $v)
{   
    echo $v.'<br />'; 
    }
}
getCountries();

Answer 1

试试这个：

foreach($countries as $v)
{   
    // I am assuming $v is an array with `ID` and `Description` in it:
    echo $v['id']."  ".$v['description'].'<br />'; 
}

这是因为项目的json是：

"item":
   [{"id":"DE","description":"Deutschland"},
    {"id":"ES","description":"EspaÃ±a"},
    {"id":"FR","description":"France"},
    {"id":"PT","description":"Portugal"},
    {"id":"UK","description":"United Kingdom"},
    {"id":"US","description":"United States"}]

其中每个项目在数组中包含id和description

Answer 2

您收到该输出是因为$v是一个数组，您必须引用$v的特定键才能看到值，例如$v['id']。您可以通过$v而不是回显来查看print_r($v);的键/值。

Answer 3

echo $v['id'] . '-' . $v['description'];

获取两个值的数组问题
