PHP无法将字符串偏移量用作数组错误

Question

我正在尝试从Rembmer the Milk API中检索任务。 我运行以下代码：

$array = json_decode($content, true);

foreach($array['rsp']['tasks']['list']['taskseries'] as $keys=>$val) {
$task = $val['name'];
$duedate = $val['task']['due'];
echo $task." ";
echo $duedate."<br>";
}

但我收到此错误：
致命错误：无法在第66行的C：**中将字符串偏移量用作数组
（第66行是$ duedate = $ val ['task'] ['due'];）

这是我尝试解码的JSON响应（试图获取“名称”：“ SOMETHING”和“到期”：“ 2011-03-17T04：00：00Z”：

{"rsp":{"stat":"ok","tasks":{"rev":"[CODE]","list":{"id":"[ID NUMBER]","taskseries": {"id":"ID","created":"DATE CREATED","modified":"DATE","name":"SOMETHING","source":"js","url":"","location_id":"","tags":[],"participants":[],"notes":[],"task":{"id":"ID","due":"2011-03-17T04:00:00Z","has_due_time":"0","added":"DATE","completed":"","deleted":"","priority":"1","postponed":"0","estimate":""}}}}}}

怎么修？ 谢谢！！！！！

UPDATE这是两个或多个任务的JSON响应：

{"rsp":{"stat":"ok","tasks":{"rev":"NUMBER","list":{"id":"ID NUMBER","taskseries":[{"id":"ID NUMBER","created":"CREATED DATE","modified":"DATE","name":"TASK 3","source":"js","url":"","location_id":"","tags":[],"participants":[],"notes":[],"task":{"id":"ID","due":"2011-03-18T04:00:00Z","has_due_time":"0","added":"DATE","completed":"","deleted":"","priority":"1","postponed":"0","estimate":""}},{"id":"ID","created":"DATE","modified":"DATE","name":"SOMETHING","source":"js","url":"","location_id":"","tags":[],"participants":[],"notes":[],"task":{"id":"ID","due":"2011-03-17T04:00:00Z","has_due_time":"0","added":"DATE","completed":"","deleted":"","priority":"1","postponed":"0","estimate":""}}]}}}}

尝试这个：

$taskSeries=$array['rsp']['tasks']['list']['taskseries'];
if(array_key_exists('id', $taskSeries)) {
    $taskSeries=array($taskSeries);
}
foreach($taskSeries as $task) {
    $name=$task['name'];
    $due=$task['task']['due'];
    // do something with $name and $due here
}
