从JSON到PHP Foreach循环的日期/时间对象

Question

我已经在堆栈上尝试了许多示例，但我似乎无法正确解决这个问题！ 我试图从该DateTime对象中提取日期，也是两行时间的原因是因为我尝试了不同的方法并比较了返回值。

[created] => DateTime Object
                (
                    [date] => 2019-06-06 15:22:25.720000
                    [timezone_type] => 1
                    [timezone] => +00:00
                )

但是由于某种原因，我得到了完全错误的日期和时间。

19-09-04 22:37:18
1970-01-01 01:00:00

19-09-04 22:37:18
1970-01-01 01:00:00

19-09-04 22:37:18
1970-01-01 01:00:00

19-09-04 22:37:18
1970-01-01 01:00:00

我尝试了以下操作：从JSON数组到PHP DateTime 从字符串 数组 到PHP 日期时间 -foreach带来->致命错误：无法使用类型的对象

PHP代码：

<?php 
    $vPaccomments = $issue->fields->comment->comments;

    foreach ($vPaccomments as $vPaccomment) {
        $vPacAvatarUrl = $vPaccomment->author->avatarUrls;
        $size16 = "16x16";
        $vPacCreated = $vPaccomment->created;
        $vPacDate = $vPacCreated->date;
        $vPacDateConv = date('Y-m-d H:i:s',strtotime($vPacDate));

        $dateTime = new DateTime($vPacDate);
        echo $dateTime->format('y-m-d H:i:s');

        echo '<pre>'; print_r($vPacDateConv);

        echo "<div class=\"col\">";
        //echo "<img width=\"16px\" src=\"" . $vPacAvatarUrl[$size16] . "\"> " . "<font color=\"#0015ff\">" .$vPaccomment->author->displayName ."</font> added a comment - " . date_format($vPacCreateDate, 'Y-m-d H:i:s');    
        echo "<br>";
        echo "<hr>";
        echo "</div>";
    }

?>

如果我echo '<pre>'; print_r($vPacCreated); echo '<pre>'; print_r($vPacCreated);

我得到想要抓住的正确结果

DateTime Object
(
    [date] => 2019-06-06 15:22:25.720000
    [timezone_type] => 1
    [timezone] => +00:00
)

DateTime Object

    [date] => 2019-06-07 13:58:31.970000
    [timezone_type] => 1
    [timezone] => +00:00
)

DateTime Object
(
    [date] => 2019-06-17 14:07:23.040000
    [timezone_type] => 1
    [timezone] => +00:00

)

这是值的一部分：

Answer 1

从您的输入数据来看， $vPacCreated看起来已经是一个DateTime对象，因此您应该能够

echo $vPacCreated->format('Y-m-d H:i:s');
