我有这个问题相关的登录页面与重定向致命错误：未捕获错误：调用未定义的函数redirect（）

Question

I want to create a login page but I'm stuck on an error. I had more errors but I went through and fixed them all except for this one which still has me lost all day so if anyone can help me I'd appreciate it, thanks.

<?php require_once("includes/header.php"); ?>

<?php
if(!$session->signin())
{
    redirect('login.php');
}
?>

these files are all working classes page

<?php

require_once ("config.php");
require_once ("database.php");
require_once ("user.php");
require_once ("functions.php");
require_once ("senssion.php");
?>

I expect to see my login page but it returns

Fatal error: Uncaught Error: Call to undefined function redirect() in

Answer 1

If you're wanting to redirect in php, the best way is using the header() function.

Syntax is:

header("Location: /examplelink");

It will then go to the page that you are wanting after your link, if you want the home directory you do not put anything after the slash. E.g:

header("Location: /");

Hope this helps :)
