Question

我正在尝试为人们在我的简单博客网站上发布的帖子加盖时间戳。我只是希望时间戳位于帖子的底部。我现在正在使用它，但是一旦我发布新帖子，最近帖子的所有时间戳都会更新到新帖子的时间戳。不知道如何解决这个问题，我尝试了不同的php时间戳等，但仍然没有去。在此先感谢帮助我！

这是我的PHP

 <!DOCTYPE HTML>
<html>
<head>
<link type="text/css" rel="stylesheet" href="post.css" />

<meta name="viewport" content="width=device-width" />
<title>Daily Dorm News</title>
</head>

<body>
<h1>Your Daily Dorm News Post! </h1>
<div id="container"> <?php if ( isset($_GET['name']) and preg_match("/^[A-Za-z0-9]+$/", $_GET['name']) ) {

    echo $_GET['name'];

} else {

    echo "You entered an invalid name!\n";

}

?><br>


Your email address is: <?php if ( isset($_GET['email']) and preg_match("/.+@.+\..+/i", $_GET['email']) ) {

    echo $_GET['email'];

} else {

    echo "You didn't enter a proper email address!\n";

}

You Posted : <?php if ( isset($_GET['message']) and preg_match("/^[A-Za-z0-9]+$/", $_GET['message']) ) {

    echo $_GET['message'];

} else {

    echo "The message is not valid! The message box was blank or you entered invalid symbols!\n";

}

This event happened :<?php echo $_GET["date"]; ?><br>

Answer 1

除非覆盖，否则日期函数默认为当前时间戳。

//echo date('l jS \of F Y h:i:s A');
echo date('l jS \of F Y h:i:s A', strtotime( $date ));

Answer 2

您未向日期功能提供帖子上的日期。如果您没有将帖子上的日期作为第二个参数提供，那么它每次只会打印今天的日期。如果你的日期没有存储，你需要首先使用strtotime（）进行转换。

date_default_timezone_set('EST');
echo date('l jS \of F Y h:i:s A', strtotime($date));

无法获得帖子的时间戳以保持正确发布
