PHP dns_check_record() function (with example)

Hey everyone,

I stumbled upon this thread and wanted to add my two cents regarding the `dns_check_record()` function in PHP.

In one of my recent projects, I had a similar need to validate DNS records, specifically TXT records. I found that `dns_check_record()` came in handy for this task.

Let me share a snippet of code to show you how I used it:

php
$domain = 'example.com';

$recordType = 'TXT';



$result = dns_check_record($domain, $recordType);



if ($result) {

    $txtRecords = dns_get_record($domain, DNS_TXT);

    

    // Loop through the TXT records

    foreach ($txtRecords as $txtRecord) {

        echo "TXT record found: " . $txtRecord['txt'] . "\n";

    }

} else {

    echo "No valid {$recordType} record found for {$domain}.";

}

Hey there!

I've actually used the `dns_check_record()` function in PHP recently, so I thought I'd chime in and share my experience with you.

To give you some context, I was working on a project where I needed to verify the existence of an MX record for a given domain. I decided to use `dns_check_record()` to accomplish this task.

Here's an example code snippet that shows how I used the function:

php
$domain = 'example.com';

$recordType = 'MX';



$result = dns_check_record($domain, $recordType);



if ($result === false) {

    echo "No valid {$recordType} record found for {$domain}.";

} else {

    echo "Valid {$recordType} record found for {$domain}!";

}

Hey folks,

I came across this thread and wanted to share my personal experience with the `dns_check_record()` function in PHP. I encountered a unique situation where I needed to verify the existence of a specific DNS record type: CAA (Certification Authority Authorization).

Here's a code snippet demonstrating how I utilized `dns_check_record()` in this case:

php
$domain = 'example.com';

$recordType = 'CAA';



$result = dns_check_record($domain, $recordType);



if ($result) {

    $caaRecords = dns_get_record($domain, DNS_CAA);



    if (!empty($caaRecords)) {

        echo "CAA records found for {$domain}:\n";



        foreach ($caaRecords as $caaRecord) {

            echo "Flag: {$caaRecord['flag']}, Tag: {$caaRecord['tag']}, Value: {$caaRecord['value']}\n";

        }

    } else {

        echo "No CAA records found for {$domain}.";

    }

} else {

    echo "No valid {$recordType} record found for {$domain}.";

}
