How to make a redirect in PHP?

Say the user goes to www.example.com/page.php and I want to redirect them to www.example.com/index.php, how would I do so without the use of a meta refresh? Is it possible?

This could even protect my pages from unauthorized users.

You can use session variables to control access to pages and authorize valid users as well:

<?php
    session_start();

    if (!isset( $_SESSION["valid_user"]))
    {
        header("location:../");
        exit();
    }

    // Page goes here
?>

http://php.net/manual/en/reserved.variables.session.php.

Recently, I got cyber attacks and decided, I needed to know the users trying to access the Admin Panel or reserved part of the web Application.

So, I added a log access for the IP address and user sessions in a text file, because I don't want to bother my database.

There are two ways to redirection

Using PHP

<?php 

header("Location: http://example.com/page.php");
die();
?>

Using Jquery

$(document).ready(function(){ location.href = 'http://example.com/page.php'; });
