PHP中页面自动刷新后的增量计数器

Question

I am very new to front end development so I am sorry if this is stupid. 我对前端开发非常陌生，所以对不起，我感到抱歉。 I am writing a webpage to display some info and I have the page auto refresh however, I would like to keep a counter static (ie not default to 0 after every refresh. What I have so far is 我正在写一个网页以显示一些信息，并且页面自动刷新，但是，我想保持一个计数器不变（即每次刷新后不默认为0。到目前为止，我有

<html>
<head>
    <title>PAGE</title>
    <link rel=StyleSheet href=css/mycss.css type="text/css">
    <meta http-equiv="refresh" content="20">
</head>

<?php
session_start();
$_SESSION['count'] = 0;
echo "<body>"
$output = "";

$output .= "<div class=\"page_title .sb-con\">DASHBOARD</div>

if(isset($_SESSION['count']) )
{
    echo "{$_SESSION['count']}\n";
$_SESSION['count'] = $_SESSION['count'] + 1;
}else{
    $_SESSION['count'] = 0;
}
echo $output;

echo "</body>";
echo "</html>";

?>

thanks in advance! 提前致谢！

If you need to get this per user, then you can use PHP sessions : 如果您需要按用户获得此权限，则可以使用PHP 会话：

The trick is to start a session, and then use $_SESSION global array to store your informations. 诀窍是开始一个会话，然后使用$_SESSION全局数组存储您的信息。 You can see simple examples of what you need here 您可以在这里看到所需的简单示例

But if you need to store this information globally, for all users, then you will have to use a database. 但是，如果您需要针对所有用户全局存储此信息，则必须使用数据库。 You can have a look at this tutorial . 您可以看一下本教程。 You will find everything you need to understand and begin with MySQL. 您将找到需要了解的所有内容，并从MySQL开始。

Your code is ok but: 您的代码还可以，但是：

1. session_start(); 1. session_start(); you place it first and after ...<html><title>PAGE</title> 您将其放在...<html><title>PAGE</title> ，然后...<html><title>PAGE</title>

2.you dont need: $_SESSION['count'] = 0 ; 2.您不需要： $_SESSION['count'] = 0 ; after session_start(); 在session_start();

Your code increment:$_SESSION['count'] , it works. 您的代码increment:$_SESSION['count'] ，它可以工作。
