How to implement jump page using php function

With the increasing development of Internet technology, website development has attracted more and more attention. In the development process of the website, page jump is a very important and commonly used function. This article will introduce how to use PHP functions to implement page jumps.

1. What is page jump

Page jump means that after clicking a specific link or button on the current page, the page will automatically jump to another page. Normally, we implement page jumps by writing code. Using PHP functions is one of the simplest and most commonly used methods.

It is very simple to use PHP functions to implement page jumps. The following is a sample code:

header('location: http://www.example.com/');

In the above code, we use PHP's "header()" function to achieve page jump. The principle is that when the browser requests a certain page, a "Location" option is added to the response header returned by the server. This option tells the browser which page it needs to jump to. Therefore, when implementing page jump, we only need to add the above code in the PHP file.

It should be noted that in order to ensure the normal use of the jump page function, the above code must be executed before all other output content, as shown below:

<?php
header(&#39;location: http://www.example.com/&#39;);
exit;
?>

In the above code, we The "exit" command has been added because the server can correctly execute the jump page command even if there is an output command in the PHP script.

3. Common jump page usage scenarios

<?php
header(&#39;location: http://www.example.com/user/profile/&#39;);
exit;
?>

2. Jump to a specific page after the user clicks a link.

<?php
header(&#39;location: http://www.example.com/product/details/123/&#39;);
exit;
?>

Through the introduction of this article, we can find that it is very simple to use PHP functions to achieve page jumps. Just add the "header()" function in the PHP file and set the jump address.
