With the development of web development, pop-up windows are an essential component in many websites or applications. However, in some cases, we need to pop up a prompt box after the user clicks confirmation and then automatically jump to another page. In this article, we will discuss how to automatically jump to another page in 3 seconds using PHP.

Step 1: Create an HTML page

First, we need to create an HTML page that contains a button and a JavaScript function to pop up a prompt box. In this example, we will use "index.html" as our HTML file name. Here is an example of HTML code:

<!doctype html>
<html>
<head>
    <meta charset="UTF-8">
    <title>PHP弹窗3秒跳转</title>
</head>
<body>

<button onclick="showAlert()">点击我</button>

<script>
function showAlert() {
    alert("您即将被重定向到另一个页面！");
}
</script>

</body>
</html>

Copy after login

This code will create a simple HTML page with a single click button. When the user clicks the button, the JavaScript function "showAlert()" will pop up a prompt box telling the user that they will be redirected to another page.

Step 2: Create a PHP page

Now, we need to create a PHP page that will redirect the user to another page. In this example, we will use "redirect.php" as our PHP file name. The following is an example of PHP code:

<?php
header(&#39;Refresh: 3; URL=http://www.example.com&#39;);
echo &#39;您即将被重定向到另一个页面，请稍候……&#39;;
exit;
?>

Copy after login

This code uses the "header()" function in PHP to redirect the user to another page. Here, we are redirecting the user to "http://www.example.com" and we will also use the "Refresh" HTTP response header to specify the refresh time of the page. In this example, we set the redirect time to 3 seconds. Finally, use the "echo" command to display a message informing the user that they will be redirected to another page, and use the "exit" command to end the execution of the page.

Step 3: Link the PHP page with the HTML page

Now, we have created an HTML page and a PHP page. Finally, we need to link them together so that when the user clicks the button, they are redirected to another page. The following is an example of the code:

<!doctype html>
<html>
<head>
    <meta charset="UTF-8">
    <title>PHP弹窗3秒跳转</title>
</head>
<body>

<button onclick="showAlert()">点击我</button>

<script>
function showAlert() {
    alert("您即将被重定向到另一个页面！");
    window.location.href = "redirect.php";
}
</script>

</body>
</html>

Copy after login

This code will call the JavaScript function "showAlert()", which will pop up a prompt box to inform the user that they will be redirected to another page. Then, use the window.location.href command to redirect the user to the PHP page "redirect.php".

Summary

The above is how to use PHP to automatically jump to another page within 3 seconds. Using this approach, you give the user time to view the message in the tooltip and give them enough time to be ready to be redirected to another page. Whether you're creating your own website or building your own app, this approach may help you.
