Gosh, I chaged my ID string to meet your suggestions some time (years?) ago.
It seems that it is not enough, anyway. :-)

Why use JS for cookies ?

You can use php objects saving, which I have recently developed. or PHP sessions.

Php objects saving class:

==> data.php <==
<?php

class Dobj {
function getNameOfClass()
{
return static::class;
}
}

class Data {

var $dtables;

function gettime() {
return date("d.m.Y H:i:s");
}

function loadobjecttables() {
$dtables = array();
foreach (glob("*.dat") as $file) {
$path_parts = pathinfo($file);
if(!class_exists($path_parts['filename'])) {
continue;
}
$file1 = file_get_contents($file, true);
$dtables[] = unserialize($file1);
}
$this->dtables=$dtables;
}

function deleteotable($otabname) {
if (file_exists($otabname.".dat")) {
unlink($otabname.".dat");
}
$this->loadobjecttables();
}

$oarridx=-1;
for($i=0; $i<count($tabls); $i++) {
if($tabls[$i][0]->getNameOfClass()==$oclass) {
$oarridx=$i;
}
}
if($oarridx==-1) return false;
$tabls[$oarridx][]=$obj;
unlink($oclass.".dat");
$b=serialize($tabls[$oarridx]);
$fh = fopen($oclass.".dat", "a");
fwrite($fh, $b);
fclose($fh);
chmod($oclass.".dat", 0700);
}
