Random redirect with the help of PHP

Question

i am trying to make random redirect using header refresh in PHP. for some reason i cannot use header location .

The code placed in example.org

$url = array('https://example.com/','https://example.net/');
shuffle($url);
header("refresh: 0;url=$url");

This redirecting to example.org/Array instead of the urls

If i use like header("refresh: 0;url=$url[0]"); it redirecting to example.com but i want to make it random.

Answer 1

To select random value from array first you need to select random key from array and then value like this

$url = array('https://example2.co/','https://example33.net/');
$key = array_rand($url);
$new_url = $url[$key];

header("refresh: 0;url=$new_url");

Answer 2

With only two items in the array you're quite likely to get the same thing every time.

You could do something like this with array_rand

$url = array('https://example.com/','https://example.net/');
$key = array_rand($url, 1);
header("refresh: 0; url={$url[$key]}");

Answer 3

You can create an array of URLs & just shuffle between those to pick at random. Then once one is picked you can header refresh to that URL:

    $url = array('https://google.com/','https://yahoo.com/');
    shuffle($url);
    $rand_url = $url[rand()&1];
    header("refresh: 0;url=$rand_url");

Answer 4

This works for me

$url = ['https://example.com','https://example.net'];
        $size = count($url);
        $random=rand(0, $size - 1);
        header("refresh: 0;url=$url[$random]");
