Different redirects per day of the week

Question

<?php

 $site[] = 'youtube.com';
 $site[] = 'facebook.com';

$destino = rand(0, (count($site) - 1));

header("Location: " . $site[$destino]);
?>

Guys, I use this script to do a random redirect. The script will choose between the two variables and will redirect, simple. But I wanted help to change this per day. Example, on Monday the variables would be

$site[] = 'youtube.com';
$site[] = 'facebook.com';

On Tuesday would be

$site[] = 'exemplo.com';
$site[] = 'mangaonli.com';

And so on. Someone could help me?

First you will make an array, with the days of the week in English containing an array of links for each day of the week, here in the example I am using the first 3 letters because I will use date("D"), but it could be the full name to use date("l") or even numbers of 0-6 to use date("w"):

$dias_e_links=array(
    "Mon"=>array(
        "link1.com",
        "link2.com",
        "link3.com"
    ),
    "Tue"=>array(
        "link1.com",
        "link2.com",
        "link3.com"
    ),
    "Wed"=>array(
        "link1.com",
        "link2.com",
        "link3.com"
    ),
    "Thu"=>array(
        "link1.com",
        "link2.com",
        "link3.com"
    ),
    "Fri"=>array(
        "link1.com",
        "link2.com",
        "link3.com"
    ),
    "Sat"=>array(
        "link1.com",
        "link2.com",
        "link3.com"
    ),
    "Sun"=>array(
        "link1.com",
        "link2.com",
        "link3.com"
    ),
);

Now just take today and give the rand() at the links:

$hoje = date("D");
$destino = rand(0, (count($dias_e_links[$hoje]) - 1));
header("Location: " . $dias_e_links[$hoje][$destino]);

Remembering that it is only one of the possible ways, but I found the simplest
