Parse a cookie string as set in a Set-Cookie HTTP header and return an associative array of data.
string $cookie Cookie header value to parse:
string $host Host of an associated request:
string $path Path of an associated request:
bool $decode Set to TRUE to urldecode cookie values:
array|bool Returns FALSE on failure or returns an array of arrays, with each of the sub arrays including:
