PHP - 如何使用Php获取json api的值？

Question

我对json有一个问题..我试图从其他网站获取api并将其作为json文件下载..我已经使用下面的代码解码了这个文件..

$str = file_get_contents('../trelloApi.json');
$json = json_decode($str, true);
echo '<pre>' . print_r($json, true) . '</pre>';

从附上的图片中，我如何获取或打印[list] =＆gt;的值？数组，[board] =＆gt;数组和[卡] =＆gt;阵列

请帮帮我:(

Answer 1

看起来api返回一个数组数组，然后使用foreach迭代json_decode。

foreach ($json as $ticket) {
    // if your $ticket['data'] is a StdClass, force to be array
    $ticket['data'] = (array)$ticket['data'];

    // now you can access your indexes
    $list = $ticket['data']['list'];
    $board = $ticket['data']['board'];
    $card = $ticket['data']['card'];
}

如果您不希望将$ticket['data']作为数组，请将其用作对象$ticket['data']->list, $ticket['data']->board...

Answer 2

在json_decode之后，您可以通过这种方式检索＆＃39;，＆＃39; board＆＃39;和＆＃39; card＆＃39;数组数据....可能会帮助你..

$list=array();
$board=array();
$card=array();

foreach($json as $key => $value){

   $list[]=$value[$key]['data']['list'];
   $board[]=$value[$key]['data']['board'];
   $card[]=$value[$key]['data']['card'];    
}

echo "<pre>";
print_r($list);
print_r($board);
print_r($card);

Answer 3

您可以访问以下列表数组：

$list = $json['data']['list']

访问板阵列：

$board = $json['data']['board']

访问卡片阵列：

$card = $json['data']['card']

Answer 4

您只能访问173个locaions数组：

$list = $json[173]['data']['list'];
$board = $json[173]['data']['board'];
$card = $json[173]['data']['card'];

print_r($list);
print_r($board);
print_r($card);

你可以得到像

这样的所有数组

foreach ($json as $key => $value) { 
    $list[] = $value['data']['list'];
    $board[] = $value['data']['board'];
    $card[] = $value['data']['card'];
}

print_r($list);
print_r($board);
print_r($card);
