如何使用dns_get_record（）搜索多个域名扩展

Question

I am trying to verify multiple domain names or extensions using dns_get_record() .

what I have tried to achieve is this.

this will only check for single domain or extension.

$name_domain = trim($_POST['domain_name']).$_POST['suffix'];
$response = @dns_get_record($name_domain, DNS_ALL);
if(empty($response)){
            $msg = "<h2 style='color:green;' >Domain $name_domain is available.</h2>";
}else if(!empty($response)){
            $msg = "<h2 style='color:red;'>Domain $name_domain has taken.</h2>";
}
echo $msg;

and this is I tried to check for multiple domain names if they are available or not.

I also want to show that domain names to echo if they are available like parwest.com, parwest.org, parwest.net if this all are available it should be echo as I tried to do.

else if these are not available or any of from this is not available then that also echo as I showed.

$name_domain = trim($_POST['domain_name']).$_POST['suffix'];
$domains = array( trim($_POST['domain_name']).'.com', trim($_POST['domain_name']).'.net' ,trim($_POST['domain_name']).'.org',);

$response = @dns_get_record(implode(' ',$domains), DNS_ALL);
if(empty($response)){
            $msg = "<h2 style='color:green;' >Domain ".implode('<br>', $domains)." is available.</h2>";
}else if(!empty($response)){
            $msg = "<h2 style='color:red;'>Domain ".implode('<br>', $domains)." has taken.</h2>";
}

but its not working. :(

any idea how can I do this?

$name_domain = trim($_POST['domain_name']).$_POST['suffix'];
$domains = array( trim($_POST['domain_name']).'.com', trim($_POST['domain_name']).'.net' ,trim($_POST['domain_name']).'.org',);

$msg='';
foreach($domains as $d){

$response = @dns_get_record($d, DNS_ALL);
if(empty($response)){
            $msg .= "<h2 style='color:green;' >Domain $d is available.</h2>";
}else if(!empty($response)){
            $msg .= "<h2 style='color:red;'>Domain $d has taken.</h2>";
}

}
