Redirect to another page with a message

I want to redirect to a page and then display a message:

What I have is:

//succes            
$message = 'succes';
redirect_to('index.php');

On the index page I have:

if (!empty($message)) {
    echo '<p class="message"> '.$message.'</p>';
}

The redirect function is working fine:

function redirect_to( $location = NULL ) {
    if ($location != NULL) {
        header("Location: {$location}");
        exit;
    }
}

But it won't display my message. It's empty.

You can use sessions

//succes            
$_SESSION['message'] = 'succes';
redirect_to('index.php');

And on index

if (!empty($_SESSION['message'])) {
    echo '<p class="message"> '.$_SESSION['message'].'</p>';
    unset($_SESSION['message']);
}

By the time the redirect happens and the PHP script depicted by $location is executed, $message variable would have been long gone.

To tackle this, you need to pass your message in your location header, using GET variable:

header("Location: $location?message=success");

And 

if(!empty($_GET['message'])) {
    $message = $_GET['message'];
// rest of your code

You could also have a look into sessions

session_start();
$_SESSION['message'] = 'success';
header("Location: $location");

then in the destination script:

session_start();
if(!empty($_SESSION['message'])) {
   $message = $_SESSION['message'];
   // rest of your code

you can avoid redirect function and use this code in the page

header("Location: $locationpage?message=success")

index.php

if(!empty($_GET['message'])) {
$message = $_GET['message'];
 echo '<p class="message"> '.$message.'</p>';
}

use the following code....

header("Location: index.php?message=success");

in index.php 

$msg=$_GET['message'];
echo $msg;

Since you are running header("Location: {$location}"); the value of $location (set in the first file) is lost when index.php is loaded.

Variables cease to exist after the script ends. Each separate request, each separate PHP script invocation is an entirely new context with no data from any other invocation.

Use sessions to persist data.
