PHP Request - The requested URL /.$final_link was not found on this server

Question

I'm getting this error when I try to access my php file. It says that the link was not found on the server. I tried echoing the link it returns, I got the correct link and when I try to access it manually, it loads but when I use redirect, I get the error.

This is my code:

<?php
    session_start();

    $user_id = $_SESSION['user_id'];
    $api_id = $_SESSION['api_id'];
    $limit =  $_SESSION['limit'];

    $final_link = 'http://www.mywebsite.info/payment/public/createPayment/' .$user_id .'/' .$api_id .'/' .$limit;
    echo $final_link;
    header('Location: .$final_link');
    exit;
    unset($_SESSION["user_id"]);
    unset($_SESSION["api_id"]);
    unset($_SESSION["limit"]);
?>

Try this:

<?php
session_start();

$user_id = $_SESSION['user_id'];
$api_id = $_SESSION['api_id'];
$limit =  $_SESSION['limit'];

$final_link = 'http://www.mywebsite.info/payment/public/createPayment/' .$user_id .'/' .$api_id .'/' .$limit;
echo $final_link;
header("Location: {$final_link}"); // changed in double quotes
exit;
unset($_SESSION["user_id"]);
unset($_SESSION["api_id"]);
unset($_SESSION["limit"]);
?>

Try this:

<?php
session_start();

$user_id = $_SESSION['user_id'];
$api_id = $_SESSION['api_id'];
$limit =  $_SESSION['limit'];

$final_link = 'http://www.mywebsite.info/payment/public/createPayment/' .$user_id .'/' .$api_id .'/' .$limit;
//no echo before header()
header("Location: $final_link"); // changed in double quotes
echo $final_link;
exit;
unset($_SESSION["user_id"]);
unset($_SESSION["api_id"]);
unset($_SESSION["limit"]);
?>
