PHP不能将字符串偏移量用作数组错误答案

【问题标题】：PHP Cannot use string offset as an array ErrorPHP不能将字符串偏移量用作数组错误

【问题描述】：

我正在尝试从 Rembmer the Milk API 检索任务。我运行这段代码：

$array = json_decode($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：不能在 C:** 第 66 行将字符串偏移用作数组
（第 66 行是 $duedate = $val['task']['due'];）

这是我尝试解码的 JSON 响应（尝试获取 "name":"SOMETHING" 和 "due":"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":""}}}}}}

如何解决？谢谢！！！！！！

更新这是两个或更多任务的 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":""}}]}}}}

【解决方案1】：

试试这个：

$taskSeries=$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
}

【讨论】：

API 可以在同一个 json 代码中返回多个任务，只是不在显示的代码中......这就是我需要 foreach 循环的原因......
@01jayss：您能否更新显示包含多个任务的示例响应的问题？
我尝试运行您的代码，但出现此错误：Notice: Undefined index: name in C:\** on line 67 and Notice: Undefined index: task in C:\** on line 68 (line 67:$name=$task['name']; line 68: $due=$task['task']['due'];...谢谢！
@01jayss：哎呀，我无意中插入了一个感叹号。现在可以使用了。
