Bug->Doc #78293 [Opn]: Raw DNS resolving of MX records not supported

Edit report at https://bugs.php.net/bug.php?id=78293&edit=1 ID: 78293 Updated by: nikic@php.net Reported by: daniil at daniil dot it Summary: Raw DNS resolving of MX records not supported Status: Open -Type: Bug +Type: Documentation Problem Package: Network related Operating System: Arch linux PHP Version: 7.3.7 Block user comment: N Private report: N New Comment: This is a case of bad docs... if raw mode is used, then you need to pass the raw DNS type ID (15 for MX). The DNS_* constants cannot be used (they are a bitmask, not a single type). The correct code is: echo ("\nRaw:\n"); var_dump(dns_get_record('daniil.it', 15, $auth, $add, true)); var_dump($auth, $add); Previous Comments: ------------------------------------------------------------------------ [2019-07-15 11:03:17] daniil at daniil dot it Description: ------------ When resolving MX records with the dns_get_record function, getting the raw record data isn't supported for some reason.
