remotelyliving / php-dns example snippets


$resolver = new Resolvers\GoogleDNS();

// can query via convenience methods
$records = $resolver->getARecords('google.com'); // returns a collection of DNS A Records

// can also query by any RecordType.
$moreRecords = $resolver->getRecords($hostname, DNSRecordType::TYPE_AAAA);

// can query to see if any resolvers find a record or type.
$resolver->hasRecordType($hostname, $type) // true | false
$resolver->hasRecord($record) // true | false

// This becomes very powerful when used with the Chain Resolver



$chainResolver = new Chain($cloudFlareResolver, $googleDNSResolver, $localDNSResolver);


$foundRecord = $chainResolver->randomly()->getARecords('facebook.com')->pickFirst();


// returns the first non empty result set
$chainResolver->withFirstResults()->getARecords('facebook.com'); 

// returns the first non empty result set from a randomly selected resolver
$chainResolver->randomly()->getARecords('facebook.com'); 

// returns only common results between resolvers
$chainResolver->withConsensusResults()->getARecords('facebook.com'); 

// returns all collective responses with duplicates filtered out
$chainResolver->withAllResults()->getARecords('facebook.com'); 


$cachedResolver = new Resolvers\Cached($cache, $resolverOfChoice);
$cachedResolver->getRecords('facebook.com'); // get from cache if possible or falls back to the wrapped resolver and caches the returned records


$cachedResolver->withEmptyResultCachingDisabled()->getARecords('facebook.com');
