Question

我对此失去了视力......我无法找到解决方案而且我一直在咆哮：P

我正在使用电影数据库获取有关电影的一些信息的JSON。这是我的代码：

<?php
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://api.themoviedb.org/3/movie/tt1327773/images?api_key=MY_API_KEY");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
  "Accept: application/json"
));

$response = curl_exec($ch);
curl_close($ch);

$posters = json_decode($response, true);

    foreach ($posters as $poster) {
    $locandina = $poster[0]->posters->file_path;
    echo $locandina;
    }

?>

当然print_r($response);有效，它会打印数组。什么是行不通的..我无法得到file_path值。即使我在Trying to get property of non-object参数中添加, true，我仍然会收到json_decode！这是阵列：

[id] => 132363
[backdrops] => Array (
    [0] => stdClass Object (
        [aspect_ratio] => 1.78
        [file_path] => /zZggWJSG18wPIOrZOgV5LI12LMi.jpg
        [height] => 1080
        [iso_639_1] =>
        [vote_average] => 5.3846153846154
        [vote_count] => 2
        [width] => 1920
    )
    [1] => stdClass Object (
        [aspect_ratio] => 1.78
        [file_path] => /wYuFRYTfx5rVjyhqdf8MXdQzKAo.jpg
        [height] => 1080
        [iso_639_1] =>
        [vote_average] => 5.3479853479854
        [vote_count] => 2
        [width] => 1920
    )
    ...
)

Answer 1

要访问file_path，您需要此数组访问密钥：$ array [＆＃34; backdrops＆＃34;] [0] [＆＃34; file_path＆＃34;] - ＆gt;因为它包含在非关联数组的第一个位置作为＆＃34;的背景值＆＃34; ...检查出来（;

// convert it to an array enabling the second parameter (associative array)
$array = json_decode($json, true);

// this is the whole array
var_dump($array);

// this is the key you need to get
var_dump($array["backdrops"][0]["file_path"]);
// which is similar to (the internal pointer points to the first element):
$sub_array = current($array["backdrops"]);
var_dump($sub_array["file_path"]);

json_decode：无法获得工作
