OnlineSemanticValidator issue

[advokatb]

$validator = new \SPFLib\OnlineSemanticValidator();
// Check an online domain
$issues = $validator->validateDomain('google.com');
foreach ($issues as $issue) {
    echo (string) $issue, "\n";
}

but this code returns an empty array. Can you please take a look if everything works as expected? I'm trying to get SPF hierarchy tree with sub-elements, but no luck with the code.

Is the SPF record of google.com semantically wrong?

Is the SPF record of google.com semantically wrong?

Seems it's OK https://easydmarc.com/tools/spf-lookup/google.com?domain=google.com I want to create such tree http://prntscr.com/22g2227 but even var_dump() shows nothing:

$validator = new \SPFLib\OnlineSemanticValidator();
// Check an online domain
$issues = $validator->validateDomain('google.com');
foreach ($issues as $issue) {
    echo (string) $issue, "\n";
    echo '<pre>';
    var_dump ($issues);
    echo '</pre>';

}

Maybe I'm doing something wrong?

I can't see any relevant images there (hint: you can paste images directly here while writing a message)

var_dump() shows nothing:

The $issues variable is an empty because the SPF if correct (there's no issue).

If you want to inspect an SPF record, read here

I want to achieve such result

Can you please provide the code or point me in the correct direction about how to achieve this hierarchy tree with sub-elements?

As I wrote before, you can use the SPFLib\Decoder class.

Here's a quick and dirty example:

use SPFLib\Decoder;
use SPFLib\Term\Modifier\RedirectModifier;
use SPFLib\Term\Mechanism\IncludeMechanism;

function checkDomain(Decoder $decoder, string $domain, int $depth = 0): void
{
    $indent = str_repeat('  ', $depth);
    echo $indent, "# Domain: {$domain}\n";
    $record = $decoder->getRecordFromDomain($domain);
    echo $indent, "- record: {$record}\n";
    echo $indent, "- modifiers:\n";
    foreach ($record->getModifiers() as $modifier) {
        echo $indent, '  ', (string) $modifier, "\n";
    }
    echo $indent, "- terms:\n";
    foreach ($record->getTerms() as $term) {
        echo $indent, '  ', (string) $term, "\n";
    }
    foreach ($record->getModifiers() as $modifier) {
        if ($modifier instanceof RedirectModifier) {
            checkDomain($decoder, (string) $modifier->getDomainSpec(), $depth + 1);
        }
    }
    foreach ($record->getTerms() as $term) {
        if ($term instanceof IncludeMechanism) {
            checkDomain($decoder, (string) $term->getDomainSpec(), $depth + 1);
        }
    }
}

checkDomain(new Decoder(), 'google.com');

its output is
