PHP, Fire cookies on condition of pages - php

Question

I'm having some trouble firing cookies on the condition of what page the user visits first.
Code below fires a cookie if on pages 2641, 2998, 2949 and no cookie exists. However, how do I do it to fire a different cookie if user is on any other page on the website if no cokkies exist?
Rule: Two cookies cannot exist. Just one or the other.
Any help much appreciated :)
if (is_page([2641,2998,2949]) && !isset($_COOKIE['ppc_campaign']) && !isset($_COOKIE['organic'])) {
$ppc_cookie = "ppc_campaign";
$ppc_value = (!empty($_SERVER['HTTPS']))
? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']
: "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
$path = "/";
setcookie($ppc_cookie, strstr($ppc_value, '?'), time() + (86400 * 28), $path);
$acf_applicationLink = $ppc_value;
}
else {
}

Sounds like this is what you want. Check for cookie existence. If neither exists, check the specific page, otherwise do something else.
if (!(isset($_COOKIE['ppc_campaign']) || isset($_COOKIE['organic']))) {
if (is_page([2641,2998,2949])) {
$ppc_cookie = "ppc_campaign";
$ppc_value = (!empty($_SERVER['HTTPS']))
? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']
: "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
$path = "/";
setcookie($ppc_cookie, strstr($ppc_value, '?'), time() + (86400 * 28), $path);
$acf_applicationLink = $ppc_value;
}
else {
$organic_cookie = "organic";
$organic_value = "?campaign=_ORGANIC_";
$path = "/";
setcookie($organic_cookie, $organic_value, time() + (86400 * 28), $path);
$acf_applicationLink = $organic_value;
}
}
