Parse a cookie string into a cookie object
Description
Based on Mozilla’s parsing code in Firefox and related projects, which is an intentional deviation from RFC 2109 and RFC 2616. RFC 6265 specifies some of this handling, but not in a thorough manner.
Parameters
$cookie_header
stringrequired- Cookie header value (from a Set-Cookie header)
$name

''
$reference_time
int|nulloptionalDefault:
null
