Page delayed jump in php

When I know how to program in PHP, sometimes I submit parameters and need to jump to another page, but before jumping, there is a prompt message that needs to be output, and it stays on the prompt message for a few seconds.

Use the following two methods to implement the delay before jumping:

Method 1:

Output the prompt "Login successful, jumping...", And jump to the Baidu homepage after 3 seconds.

<?php
echo "登录成功,正在跳转....";
header("refresh:3;url=http://www.baidu.com");
?>

Method 2: Use PHP’s sleep() function

<?php
print("登录成功，正在跳转....")
sleep(3);
header(&#39;location:http://www.baidu.com&#39;);
?>
