So your cookie is not giving the relevant information to the browser for it to be accessible across subdomains and/or the directory path.

document.cookie = 'ppkcookie1=testcookie; expires=Thu, 2 Aug 2001 20:47:11 UTC; path=/; ;domain=.example.com'

Note, .example.com is just an example domain (you need yours in there), and you do not need a wildcard other than the initial . for it go across all subdomains. And you need to generate an expires= date. From QuirksMode:

function createCookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    } else {
        var expires = "";
    }
    document.cookie = name+"="+value+expires+"; path=/; domain=.example.com";
}

http://example.com/test.php

function createCookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    }
    else var expires = "";
    document.cookie = name+"="+value+expires+"; path=/; domain=.example.com";
}

createCookie('cookieee','stuff','22');

http://example.com/test/test.php

<pre>
<?php 

print_r($_COOKIE);

?>

Can you give some more information? Are they both on the same domain just different files? Is the line

document.cookie = cookieName+"="+cookieValue;

If you want to expand the domain available to the cookie you need to specify it as part of the cookie:

document.cookie = cookieName + '=' + cookieValue + '; path=/;';

For setting the cookie:

document.cookie = "key=value; expires=Fri, 03 Aug 2018 12:00:00 UTC; path=/";

For setting the cookie:

setcookie('key', 'value', (time() + (3600*2)), '/');

For accessing:

if (isset($_COOKIE['key'])) echo $_COOKIE['key'];
