How to use PHP to jump and refresh the page

With the development of the Internet, websites have become the main way for people to obtain information. In websites, jumping to pages is a very common operation. Generally speaking, we can use PHP to implement the jump function, but sometimes we need to refresh the page while jumping. Let's briefly introduce how to use PHP to jump and refresh the page.

1. PHP implements jump

1. Use header function to jump

The header function is a very commonly used function in PHP, which can send HTTP on the server side Header information, which means that page redirection can be achieved. In practice, you can use the header function to jump to other pages.

The following is the PHP code to jump to another page:

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

Among them, "Location" is the redirection status code in the HTTP protocol, followed by the page address to be jumped. . In addition, if you add exit after the header function, you can terminate the execution of subsequent code in time to avoid unnecessary errors.

2. Use the tag to jump

Although the header function can realize page jump, in some cases it is not the best choice. For example, sometimes we need to ask users to confirm certain information or complete other operations before jumping. At this time, we can use the tag in HTML to jump to the page. The following is an example of using the tag to jump to a page:

<a>跳转到example.com</a>

Among them, the "href" attribute specifies the page address to jump to, in the "" tag The content is the link text that users can click.

2. PHP implements jump and refreshes the page

Sometimes, just jumping to another page does not meet our needs. For example, users may need to see the latest page content after the jump. At this time, we need to refresh the page while jumping.

The implementation is as follows:

header('Location: http://www.example.com/');
echo "<meta>";

In this example, we first use the header function to jump to the page to example.com, and then use the tag to refresh the page. Among them, the content attribute specifies the time to refresh (in seconds), and the url attribute specifies the page address to refresh.
