It is not true which you set cookie format. You need to set cookie correctly , with path, with expires date, with name=key format. For example:
<script>
function setCookie(name,value,days) {
var expires = "";
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days*24*60*60*1000));
expires = "; expires=" + date.toUTCString();
}
document.cookie = name + "=" + (value || "") + expires + "; path=/";
}
setCookie('myKey','myVal123',7);
</script>
<?php
print_r($_COOKIE);
