php - 在 PHP 中解析数据并提取元素

Question

$pf = new Petfinder('API_KEY');
$pf->setResponseFormat('json');
$petJson = $pf->pet_find(array('output'=>'basic', 'location' => '32810', 'count' => '25'));
$pet = json_decode($petJson);
foreach ($pet as $pets)
{
    print_r($pets);
}

我试过var_dump($pets->pets->pet);了，但没有用。

我只是想提取一个元素，例如品种，任何帮助将不胜感激。

Answer 1

要获得 Breed，您需要执行以下操作。

$pf = new Petfinder('API_KEY');
$pf->setResponseFormat('json');
$petJson = $pf->pet_find(array('output'=>'basic', 'location' => '32810', 'count' => '25'));
$pet = json_decode($petJson);

变量转储

var_dump($pet->pets->pet->breeds->breed);

Answer 2

您可以将此对象转换为数组并使用数组函数，请尝试使用此代码进行转换。

if (is_object($pets)) {
    $pets_arr = get_object_vars($pets);
    var_dump($pets_arr);
}

Answer 3

这是我如何解析品种的方法。

    var_dump($pet->petfinder->pets->pet->breeds->breed)

   array(2) { [0]=> object(stdClass)#25 (1) { ["$t"]=> string(19) "Domestic Short Hair" }          [1]=> object(stdClass)#26 (1) { ["$t"]=> string(36) "Domestic Short Hair -Gray And White" } }
