PHP page jump and routing management in mini program development

With the rapid development of mini programs, more and more developers are beginning to combine PHP with mini program development. In the development of small programs, page jump and routing management are very important parts, which can help developers achieve switching and navigation operations between pages. As a commonly used server-side programming language, PHP can interact well with mini programs and transfer data. Let’s take a detailed look at PHP’s page jump and routing management in mini programs.

1. Basics of page jump

In mini program development, there are usually two ways to jump to a page: jump to a page within the application and jump to an external link.

1. Jump to the page within the application

In the mini program, you can use the wx.navigateTo and wx.redirectTo methods to jump to the page. The wx.navigateTo method will retain the current page and jump to a page within the application, while the wx.redirectTo method will close the current page and jump to a page within the application.

The following is a PHP code example:

<?php
    if($_GET['action'] == 'navigate') {
        // 跳转到应用内的页面
        header('Location: pages/index.php');
    } elseif($_GET['action'] == 'redirect') {
        // 关闭当前页面，并跳转到应用内的页面
        header('Location: pages/redirect.php');
    }
?>

2. Jump to external link

In the mini program, you can use wx.navigateTo and wx.redirectTo Method to jump to external links. What needs to be noted here is that when jumping to an external link, a legal domain name needs to be set in the background of the mini program.

The following is a PHP code example:

<?php
    if($_GET['action'] == 'navigate') {
        // 跳转到外部链接
        header('Location: https://www.example.com');
    } elseif($_GET['action'] == 'redirect') {
        // 关闭当前页面，并跳转到外部链接
        header('Location: https://www.example.com');
    }
?>

2. Routing management

In the development of small programs, routing management is a very important part, which can help developers realize the page between navigation and management. In PHP, you can use $_SERVER['REQUEST_URI'] to get the URL of the current page, and then load different pages based on different URLs.

The following is a PHP code example:

<?php
    // 获取当前页面的URL
    $currentUrl = $_SERVER['REQUEST_URI'];

    // 根据不同的URL来加载不同的页面
    switch($currentUrl) {
        case '/pages/index.php':
            // 加载首页
            include('pages/index.php');
            break;
        case '/pages/redirect.php':
            // 加载重定向页面
            include('pages/redirect.php');
            break;
        default:
            // 加载默认页面
            include('pages/default.php');
            break;
    }
?>

Through the above example, we can see that in PHP, different pages can be loaded according to different URLs, thereby realizing the routing management function. Developers can customize different URLs and corresponding pages according to actual needs.

Summary:

This article introduces the page jump and routing management of PHP in the development of small programs. Through PHP's header function, we can implement page jump and redirect operations. The URL of the current page can be obtained through $_SERVER['REQUEST_URI'], thereby realizing the routing management function. I hope this article will be helpful to your page jump and routing management in mini program development.
