25	* Fetch DNS Resource Records associated with the given
26	* hostname.
27	*
28	* @param string $hostname hostname should be a valid DNS hostname such
29	* as "www.example.com". Reverse lookups can be generated
30	* using in-addr.arpa notation, but
31	* gethostbyaddr is more suitable for
32	* the majority of reverse lookups.
33	*
34	* Per DNS standards, email addresses are given in user.host format (for
35	* example: hostmaster.example.com as opposed to hostmaster@example.com),
36	* be sure to check this value and modify if necessary before using it
37	* with a functions such as mail.
38	* @param int $type By default, dns_get_record will search for any
39	* resource records associated with hostname.
40	* To limit the query, specify the optional type
41	* parameter. May be any one of the following:
42	* DNS_A, DNS_CNAME,
43	* DNS_HINFO, DNS_CAA,
44	* DNS_MX, DNS_NS,
45	* DNS_PTR, DNS_SOA,
46	* DNS_TXT, DNS_AAAA,
47	* DNS_SRV, DNS_NAPTR,
48	* DNS_A6, DNS_ALL
49	* or DNS_ANY.
50	*
51	* Because of eccentricities in the performance of libresolv
52	* between platforms, DNS_ANY will not
53	* always return every record, the slower DNS_ALL
54	* will collect all records more reliably.
55	*
56	* DNS_CAA is not supported on Windows.
57	* @param array\|null $authns Passed by reference and, if given, will be populated with Resource
58	* Records for the Authoritative Name Servers.
59	* @param array\|null $addtl Passed by reference and, if given, will be populated with any
60	* Additional Records.
61	* @param bool $raw The type will be interpreted as a raw DNS type ID
62	* (the DNS_* constants cannot be used).
63	* The return value will contain a data key, which needs
64	* to be manually parsed.
65	* @return array This function returns an array of associative arrays. Each associative array contains
66	* at minimum the following keys:
67	*
68	* Basic DNS attributes
69	*
