In PHP development, especially in MVC frameworks or projects, you will encounter many jump situations, such as jumps after successful or failed login, etc.

The main content of this article is the implementation process of the jump prompt box based on PHP. The code is attached, friends in need can refer to it.

The following is based on the MVC framework development, with examples:

In the basic controller class: Conrtoller.class.php

<?php /**
 * 基础控制器类
 */
class Controller {
    /**
     * 跳转
     * $url 目标url
     * $info 提示信息
     * $time 等待时间（单位秒）
     */
    protected function jump($url,$info=NULL,$time=3) {
        //判断是立即跳转还是刷新跳转
        if(is_null($info)) {
            //立即跳转
            header(&#39;location:&#39;. $url);
            die;
        } else {
            //刷新跳转,给出提示
            echo <<<TIAOZHUAN
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>提示信息</title>
<style>
    * {margin:0; padding:0;}
    div {width:390px; height:287px; border:1px #09C solid; position:absolute; left:50%; margin-left:-195px; top:10%;}
    div h2 {width:100%; height:30px; line-height:30px; background-color:#09C; font-size:14px; color:#FFF; text-indent:10px;}
    div p {height:120px; line-height:120px; text-align:center;}
    div p strong {font-size:26px;}
</style>
<div>
    <h2 id="提示信息">提示信息</h2>
    <p>
        <strong>$info</strong><br>
        页面在<span>$time</span>秒后会自动跳转，或点击<a>立即跳转</a>
    </p>
</div>
<script>
    var url = document.getElementById(&#39;tiao&#39;).href;
    function daoshu(){
        var scd = document.getElementById(&#39;second&#39;);
        var time = --scd.innerHTML;
        if(time<=0){
            window.location.href = url;
            clearInterval(mytime);
        }
    }
    var mytime = setInterval("daoshu()",1000);
</script>
TIAOZHUAN;
        die;
        }
    }

}

In the automatic loading of MVC, automatically load and register Controller.class.php

After inheriting the above Controller.class.php basic controller class through different controller classes, you can call the defined jump Transfer prompt.

<?php /**
 * 后台管理员控制器(登录、注销、管理员的增删改查等)
 */
class AdminController extends Controller {
    /**
     * 展示登录表单动作
     */
    public function loginAction() {
        // 载入当前的视图文件
        $this->display('login.html');
    }
    /**
     * 后台注销功能
     */
    public function logoutAction() {
        @session_start();
        // 删除相关会话数据
        unset($_SESSION['adminInfo']);
        // 删除会话数据区
        session_destroy();
        // 立即跳转到登录页面
        $this->jump('index.php?c=Admin&a=login','您已退出后台登录！');
    }
}

Of course, this is implemented in MVC, you can also use jump() separately.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
