Title: PHP code tutorial to implement 3-second automatic jump

In web development, we often encounter the need for automatic page jump, such as when a user completes a certain Automatically jump to another page after an operation. This article will introduce how to use PHP to implement a function that automatically jumps after 3 seconds, and provide specific code examples.

First, we need to create a PHP file named redirect.php. In this file, write the following code to implement automatic page jump:

<?php
$url = 'http://www.example.com'; // 设置跳转的目标页面URL
$seconds = 3; // 设置跳转的等待时间，单位为秒
echo "页面将在{$seconds}秒后自动跳转至<a href='{$url}'>这里</a>";
header("refresh:{$seconds};url={$url}"); // 使用header函数设置自动跳转
?>

In the above code, we first define the URL of the target page and the waiting time for the jump, and then use the header function to set the automatic jump response header. After the page is loaded, a prompt message will be displayed and it will automatically jump to the target page after the specified time.

Next, deploy the redirect.php file to the web server and access the file through the browser to see the effect. The page will automatically jump to the specified URL after 3 seconds.

It should be noted that the automatic jump function may be restricted or blocked by the browser, and the specific effect may vary depending on the browser version.

Through the above simple code example, we have implemented a 3-second automatic jump function using PHP. Hope this article can help you achieve similar needs in web development.
