How to close a page and jump to a new page in php

PHP is a widely used server-side scripting language. In web development, closing a page and jumping to a page is a frequently used function. In PHP, you can use the header function to close the current page and jump to another page.

The header function is a very important function in PHP, which can send HTTP header information to the client. These header information can contain the following content:

1. Status code
2. MIME type
3. Encoding method
4. Cache control
5. Page Jump
6. Cookie settings

When implementing the function of turning off page jump, the parameter we commonly use is the fifth parameter, which is page jump. Next, we will explain in detail how to use the header function to close the page and jump to other pages.

First, we need to use the header function in PHP to send a header information that specifies the URL address of the target page to jump to. The following is the code to implement this process:

header("Location: http://www.example.com/index.php");

In this code, we use the header function and pass a Location parameter. This parameter specifies the URL address of the page to be redirected. In this example, we will jump to the page http://www.example.com/index.php.

Next, we need to exit the current page immediately after the header function, otherwise some useless information will be output, causing the page jump to fail. We can use the exit function to exit the page, as shown below:

header("Location: http://www.example.com/index.php");
exit;

In this example, we use the exit function immediately after the header function to exit the current page.

It should be noted that no content can be output before calling the header function. Otherwise, the header function will fail. If you need to output content, you can place the content after the header function call.

In short, turning off the function of page jumping to other pages in PHP can be achieved through the header function. You only need to specify the URL address of the page you want to jump to in the header function, and then exit the current page immediately.
