如何使用dns_get_record（“ example.com”，DNS_NS）检查DNS记录购买；

Question

实际上是想立即获取域列表的A和MX记录，

function DNSrecord() {
    $domaindata=array('revilossor.com,elliscaravans.co.uk,giggletricks.co.uk,peking-takeaway.co.uk,noeljoneslodge.co.uk,melissawhiting.co.uk,electric-hybrid-bikes.com,lovelightandpeacetents.com,ianpepper.co.uk,thelongmarch.com,mollyshouse.infodarrandigaba.com,assfa.co.uk,carolsugden.co.uk,eagleeyebusinesssolution.co.uk,clairewinteringham.com,kdpollard.com,projectyellowrose.com,naturalsynergyreiki.co.uk,chelonist.com,rickgriffithsreel.com,wilsons-garage.co.uk,fnlc.org.uk,mudinmyhair.co.uk,johnoatesltd.co.uk,acsd.co.uk,bristolthaimassage.co.uk,cycle-speed.com');
    //echo gethostbyname($ip);
    /* $result = dns_get_record($ip);
    foreach($result[0] as $res){
        echo $res.'<br />';
    } */

    foreach ($domaindata as $ddata){
        $ddata;
    }

    $dns = dns_get_record( $ddata, DNS_ANY );
    foreach( $dns as $d ) {
        // Only print A and MX records
        if( $d['type'] != "A" and $d['type'] != "MX" )
            continue;
        // First print all fields
        echo "For " . $d['host'] . ": <br />\n";
        switch( $d['type'] ) {
            case 'A':
                // Display annoying message
                echo "<b>\n" . $d['ip'] . "</b>\n is the Primary A Record for this domain. <br /><br />\n";
                break;
            case 'MX':
                // Resolve IP address of the mail server
                $mx = dns_get_record( $d['target'], DNS_A );
                foreach( $mx as $server ) {
                    echo "The MX record for " . $d['host'] . " points to the server <b>\n" . $d['target'] . "</b>\n whose IP address is <b>\n" . $server['ip'] . "</b>. It has a priority of <b>\n" . $d['pri'] . "</b>\n. <br /><br />\n";
                }
            if ( $d['target'] == $ddata ) {
                echo "<i>It looks like the domain is using itself as an MX Record.  You will need to create additional records.</i><br /><br />\n";
                    } else {
                echo "<i>This MX Record looks fine.</i><br /><br />\n";
                }
                break;
        }
    }

    error_reporting(E_ALL);


}

兔子是代码

当我仅进入单个域时，它的工作原理；但是当我大量使用时，它不能； t

Answer 1

首先，使用explode将字符串转换为数组：

$domaindata = 'revilossor.com,elliscaravans.co.uk,giggletricks.co.uk,peking-takeaway.co.uk,noeljoneslodge.co.uk,melissawhiting.co.uk,electric-hybrid-bikes.com,lovelightandpeacetents.com,ianpepper.co.uk,thelongmarch.com,mollyshouse.infodarrandigaba.com,assfa.co.uk,carolsugden.co.uk,eagleeyebusinesssolution.co.uk,clairewinteringham.com,kdpollard.com,projectyellowrose.com,naturalsynergyreiki.co.uk,chelonist.com,rickgriffithsreel.com,wilsons-garage.co.uk,fnlc.org.uk,mudinmyhair.co.uk,johnoatesltd.co.uk,acsd.co.uk,bristolthaimassage.co.uk,cycle-speed.com';
$domaindata = explode(',', $domaindata);

因为dns_get_record 不在 的foreach循环，它只会给记录您的阵列中的最后一项。

foreach ($domaindata as $ddata)
{
    $dns = dns_get_record( $ddata, DNS_ANY );
    //etc...
}

为什么在执行函数后启用error_reporting（）？
