我正在尝试为人们在我的简单博客网站上发布的帖子添加时间戳。我只希望时间戳位于他们帖子的底部。我现在让它工作，但是一旦我发布了一个新帖子，最近帖子的所有时间戳都会更新为新帖子时间戳。不知道如何解决这个问题，我尝试了不同的 php 时间戳等，但仍然没有。提前感谢您对我的帮助！
这是我的PHP

date 函数默认为当前时间戳，除非被覆盖。
//echo date('l jS 'of F Y h:i:s A');
echo date('l jS 'of F Y h:i:s A', strtotime( $date ));
您没有为日期函数提供帖子上的日期。如果您不提供帖子上的日期作为第二个参数，那么它每次都会打印今天的日期。如果您的日期未存储为时间，则需要先使用 strtotime（） 进行转换。
date_default_timezone_set('EST');
echo date('l jS 'of F Y h:i:s A', strtotime($date));
