当我尝试在mongodb上获取数据时，我遇到了错误

Question

我有很多这样的统计数据：

我在控制器中获取此数据时遇到此错误：

Could not convert array to a date value 

堆栈跟踪：

MongoDB映射文件中的相关字段映射：

 /**
     * @MongoDB\Date
     */
    public $logDate;
/**
     * Get logDate
     *
     * @return @MongoDb\Date $logDate
     */
    public function getLogDate()
    {
        return $this->logDate;
    }

    /**
     * Set logDate
     *
     * @param  $logDate
     * @return self
     */
    public function setLogDate($logDate)
    {
        $this->logDate = $logDate;

        return $this;
    }

首先，我问了两件关于这件事的问题。

• 为什么mongodb将日期数据存储为对象/数组？
• 我该如何修理这个狗屎？

感谢所有人的兴趣。

Answer 1

logDate是一个数组，因为它包含以下属性date，timezone_type和timezone。不知道为什么MongoDB会这样做，我从来没有真正使用它，所以我没有回答这个问题。但是，如果您还想处理时区信息，您可以将日期格式化为ISO8601并存储，然后交叉引用给定时区以获得时区的实际名称。

要修复logDate问题，您只需将其用作数组，例如logDate['date']获取实际日期时间。
