如何从 api curl php 获取特定值

Question

所以我试图从所有索引中获取“title”和“Artist->name” 我尝试了很多次，甚至使用了 foreach，但我仍在学习 curl，只能为第一个索引或特定索引获取它，这是表格

等等，这里是代码

    $ch = curl_init();
    $url = "https://api.deezer.com/search?q=broken%20strings";
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $resp = curl_exec($ch);
    if($e = curl_error($ch)){
        echo $e;
    }else{
        $decoded = json_decode($resp,true);
        print_r($decoded);
    }
    curl_close($ch);

这个帖子所有的数组

Answer 1

$decoded['data'] 将包含一个包含您所有记录的数组，因此您希望 foreach 超过它：

foreach ($decoded['data'] as $record) {

在该循环的每次迭代中，$record 将是每个单独记录的子数组。所以在第一次迭代中，$record 将是：

Array(
    [id] => 2298089
    [readable] => 1
    [title] => Broken Strings
    [title_short] => Broken Strings
    [title_version] => 
    [link] => https://www.deezer.com/track/2298089
    [duration] => 250
    [rank] => 749501
    ...

然后您可以引用该数组中的每个字段，例如$record['id'] 或$record['link']。要“深入”到多维数组，只需堆叠连续的 [] 引用，例如 $record['album']['id'] 或 $record['artist']['link']。

大家一起：

foreach ($decoded['data'] as $record) {
    printf("Title: %s\n", $record['title']);
    printf("Artist: %s\n\n", $record['artist']['name']);
}
