Edit report at https://bugs.php.net/bug.php?id=78293&edit=1 ID: 78293 Comment by: daniil at daniil dot it Reported by: daniil at daniil dot it Summary: Raw DNS resolving of MX records not supported Status: Closed Type: Documentation Problem Package: Network related Operating System: Arch linux PHP Version: 7.3.7 Assigned To: nikic Block user comment: N Private report: N New Comment: Welp too late I saw you already edited that :) Previous Comments: ------------------------------------------------------------------------ [2019-07-15 12:30:16] daniil at daniil dot it I guess I was fooled by the fact that DNS_A is equal to 1, I guess I'll edit the docs then ------------------------------------------------------------------------ [2019-07-15 12:27:25] nikic@php.net I've clarified the docs in https://github.com/php/doc-en/commit/cf08482c9e4db2497d51c4ff4acd8942e70a7b2f. ------------------------------------------------------------------------ [2019-07-15 11:20:54] nikic@php.net 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); ------------------------------------------------------------------------ [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. Test script: --------------- <?php echo ("Normal:\n"); var_dump(dns_get_record('daniil.it', DNS_MX, $auth, $add, false)); var_dump($auth, $add); echo ("\nRaw:\n"); var_dump(dns_get_record('daniil.it', DNS_MX, $auth, $add, true)); var_dump($auth, $add) Expected result: ---------------- Normal: array(1) { [0]=> array(6) { ["host"]=> string(9) "daniil.it" ["class"]=> string(2) "IN" ["ttl"]=> int(300) ["type"]=> string(2) "MX" ["pri"]=> int(10) ["target"]=> string(13) "mx.yandex.net" } } NULL NULL Raw: array(1) { [0]=> array(6) { ["host"]=> string(9) "daniil.it" ["class"]=> string(2) "IN" ["ttl"]=> int(300) ["type"]=> int(16384) ["data"]=> string(X) "binary data representing MX record" } } NULL NUL Actual result: -------------- Normal: array(1) { [0]=> array(6) { ["host"]=> string(9) "daniil.it" ["class"]=> string(2) "IN" ["ttl"]=> int(300) ["type"]=> string(2) "MX" ["pri"]=> int(10) ["target"]=> string(13) "mx.yandex.net" } } NULL NULL Raw: array(0) { } NULL NUL ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78293&edit=1
