使用特定的 DNS 处理器进行 DNS 询问
仅限 PHP >= 7.4
对于旧版 PHP 版本，我们强烈建议使用 bluelibraries/php5-dns
演示
示例
$records = DNS::getRecords('bluelibraries.com', RecordTypes::ANY); print_r($records);
Array
(
[0] => BlueLibraries\Dns\Records\Types\NS Object
(
[data:protected] => Array
(
[host] => bluelibraries.com
[ttl] => 21600
[class] => IN
[type] => NS
[target] => ns3.instradns.com
)
)
[1] => BlueLibraries\Dns\Records\Types\A Object
(
[data:protected] => Array
(
[host] => bluelibraries.com
[ttl] => 21600
[class] => IN
[type] => A
[ip] => 198.50.252.64
)
)
)
通过 composer 安装
composer require bluelibraries/dns
本包包含 4 种类型，可用于 DNS 询问
- DnsGetRecord 基于 PHP 函数
dns_get_record - Dig 基于 shell 命令
dig（比dns_get_record更好，且依然安全） - UDP 基于
rawDNS 调用使用UDP/socket- 对于短回答查询很有用，因为 UDP 答案可能限制为512字节 - TCP 基于
rawDNS 调用使用TCP/socket- 这是最优选择，并设置为默认处理器
DNS 处理器比较
DNS 处理器自定义设置
// Let's customize the DNS request handler - TCP $dnsHandler = (new TCP()) ->setPort(53) ->setNameserver('8.8.8.8') ->setTimeout(3) // limit execution to 3 seconds ->setRetries(5); // allows 5 retries if response fails // Let's initialize the DNS records service $dnsRecordsService = new DnsRecords($dnsHandler); // let's get some TXT records from `bluelibraries.com` $records = $dnsRecordsService->get('bluelibraries.com', RecordTypes::TXT); // let's display them print_r($records);
Array
(
[0] => BlueLibraries\Dns\Records\Types\TXT Object
(

(
[host] => bluelibraries.com
[ttl] => 3600
[class] => IN
[type] => TXT
[txt] => google-site-verification=kWtestq0tP8Ae_WJhRwUcZoqpdEkvuXJk

UDP 和 DIG 类似
$dnsHandler = (new UDP()) ->setPort(53) ->setNameserver('8.8.8.8') ->setTimeout(3) // limit execution to 3 seconds ->setRetries(5); // allows 5 retries if response fails $dnsHandler = (new DIG()) ->setPort(53) ->setNameserver('8.8.8.8') ->setTimeout(3) // limit execution to 3 seconds ->setRetries(5); // allows 5 retries if response fails
DnsGetRecord - 此处理器设置有限
// DnsGetRecord allows only Timeout and Retries, but there is no control over timeout // so the timeout may be much longer than the limit we set! $dnsHandler = (new DnsGetRecord()) ->setTimeout(3) // limit execution to 3 seconds ->setRetries(5); // allows 5 retries if response fails

使用 dns_get_record 获取记录
$records = DNS::getRecords('bluelibraries.com', RecordTypes::TXT, DnsHandlerTypes::DNS_GET_RECORD); print_r($records);
Array

[txt] => google-site-verification=test-636b-4a56-b349-test
)
)
)
使用 dig 获取记录
$records = DNS::getRecords('bluelibraries.com', RecordTypes::TXT, DnsHandlerTypes::DIG); print_r($records);
Array
