这段代码运行良好，为我的两篇文章中的每一篇返回两个StdClass对象：

        $children = get_pages($args);

        foreach ($children as $cake=>$element) {
            $args = array(
                          \'post_id\' => $ID
                          );
            $Comments = get_comments( $args );
        };

这太棒了。我得到了每条评论的属性，但我只对评论日期感兴趣。我想要的输出是：

$CommentDates=（date1、date2等）——最终我想得到最近的评论日期。

我的下一步行动是：

        foreach ($Comments as $CommentObject) {
            $CommentDates = $CommentObject->comment_date;
        }

这只返回一个日期，它恰好是第二个对象的值。

然而，如果我简单地重复这个foreach，我会得到两个日期。

foreach（$Comments as$CommentObject）{echo$CommentObject->comment\\u date；}

// Not sure what purpose your $cake and $element serve here )
foreach( $children as $cake => $element ) {
  $args = array( \'post_id\' => $ID ); // Assuming this $ID is declared elsewhere
  $comments[] = get_comments( $args );
}

foreach( $comments as $commentObject ) {
  $commentDates[] = $commentObject->comment_date;
}

$CommentDates = array();
foreach ( $Comments as $Comment ) {
    $CommentDates[] = $Comment->comment_date;
}

$CommentDates = \'\';
$length = count( $Comments );
for ( $i = 0, $i < $length, $++ ) {
    $CommentDates .= $Comment->comment_date;
    if ( ! $i == ( $length - 1 ) ) {
        $CommentDates .= \', \';
    }
}
