Title: PHP programming skills: How to jump to a web page within 3 seconds

In web development, we often encounter the need to automatically jump to a page within a certain period of time case of another page. This article will introduce how to use PHP to implement programming techniques to jump to a page within 3 seconds, and provide specific code examples.

First of all, the basic principle of page jump is achieved through the Location field in the HTTP response header. By setting this field, the browser can automatically jump to the specified page.

The following is a simple example that demonstrates how to automatically jump to another page within 3 seconds in PHP:

<?php
// 设置要跳转的目标页面
$targetUrl = "https://www.example.com/target-page";

// 设置跳转的延迟时间，这里设置为3秒
$delay = 3;

// 发送响应头，告诉浏览器进行跳转
header("Refresh:$delay;url=$targetUrl");

// 在页面中显示提示信息，告诉用户将在几秒后跳转
echo "<h1 id="页面将在-delay-秒后自动跳转到-a-href-targetUrl-targetUrl-a">页面将在 $delay 秒后自动跳转到 <a href='$targetUrl'>$targetUrl</a></h1>";
?>

In the above code, first set the settings to jump to The target page $targetUrl, and then set the jump delay time $delay, here it is set to 3 seconds. Then use the header() function to send the HTTP response header, and set the jump delay time and the URL of the target page in the Refresh field. Finally, a prompt message is displayed on the page, informing the user that it will automatically jump to the specified page in a few seconds.

Through the above code example, you can realize the function of automatically jumping to another page within 3 seconds. Developers can adjust and customize according to actual needs to achieve a more flexible page jump effect that meets project needs.
