我正在开发一个Jira项目，我正在从API查询中返回一个数据。数据是json_encode格式。
我在访问数组中的数组时遇到问题。
这是我正在使用的json_encode数据。

这是我的片段PHP代码，用于访问记录和打印。
foreach ($json_output->issues as $issues) {
echo "{$issues->key}";
echo "{$issues->fields->summary}";
echo "{$issues->fields->created}";
echo "{$issues->fields->reporter->name}";
}
现在，当我想访问customfield_11054时，我可以打印服务器列表
server1, server2, server3, server4, server5, server6, server7, server8, server9, server10,
server11, server12, server13
所以我添加了这个
foreach ($json_output->issues as $issues) {
echo "{$issues->key}";
echo "{$issues->fields->summary}";
echo "{$issues->fields->created}";
echo "{$issues->fields->reporter->name}";
echo "{$issues->fields->customfield_11054}";
}
但我得到的结果是数组。
答案 0 :(得分：4)
print_r($issues->fields->customfield_11054);
这是一个数组，这就是为什么它说它是一个数组。如果你想获得价值，你必须在那里包装另一个foreach：
foreach ($json_output->issues as $issues) {
echo $issues->key;
echo $issues->fields->summary;
echo $issues->fields->created;
echo $issues->fields->reporter->name;
foreach($issues->fields->customfield_11054 as $customField)
{
echo $customField;
}
}
另外，作为附注，您不需要将变量放在“{}”中以将其打印出来。它们是字符串，所以只使用echo $variable;就可以正常工作（就像我在上面的snippit中所做的那样）。
答案 1 :(得分：0)
为简单起见使用此
$data = json_decode($result,true);
foreach ($data as $values) {
//then do stuff here
}
答案 2 :(得分：0)
使用implode功能
foreach ($json_output->issues as $issues) {
echo "{$issues->key}";
echo "{$issues->fields->summary}";
echo "{$issues->fields->created}";
echo "{$issues->fields->reporter->name}";
echo implode(',', $issues->fields->customfield_11054);
}
