note 119579 added to function.dns-get-record

I found that this code does not get the correct records all the time (at least not our PHP version). It has something to do with CNAMES therefore, you should do something like this: <?php function dns_get_valid_record($domain, $type=DNS_MX, $root = 0){ $result = dns_get_record("".$domain."", $type); //first try to find it this way. if(!$result){ //check for cname; $result = dns_get_record("".$domain."", DNS_CNAME); //check if it is a cname, and if so, try that domain. if($result && $result[0]["target"]){ return dns_get_valid_record($result[0]["target"],$type); }else{ //if not, translate www.example.com to example.com, and try again. $domain = explode(".", $domain); if(count($domain)>2 && $root==0) { $domain = $domain[count($domain) - 2] . "." . $domain[count($domain) - 1]; return dns_get_valid_record($domain, $type,1); } } }else { foreach($result as $key=>$record){ if(isset($record["target"]) && !filter_var($record["target"], FILTER_VALIDATE_IP)){ //no ip? if(!dns_get_valid_record($record["target"], DNS_A)){ //we validated one: check if we get anywhere (A or CNAME=>A) unset($result[$key]); } } } } return $result; } ?> you can look up anything else, but this is primarily designed for getting MX records and test if they could exist. the IP address could still not be in the air or not the correct one, but DNS will be properly setup when returned results. ---- Server IP: 72.52.91.14 Probable Submitter: 83.86.92.251 ---- Manual Page -- http://php.net/manual/en/function.dns-get-record.php Edit -- https://master.php.net/note/edit/119579 Del: integrated -- https://master.php.net/note/delete/119579/integrated Del: useless -- https://master.php.net/note/delete/119579/useless Del: bad code -- https://master.php.net/note/delete/119579/bad+code Del: spam -- https://master.php.net/note/delete/119579/spam Del: non-english -- https://master.php.net/note/delete/119579/non-english Del: in docs -- https://master.php.net/note/delete/119579/in+docs Del: other reasons-- https://master.php.net/note/delete/119579 Reject -- https://master.php.net/note/reject/119579 Search -- https://master.php.net/manage/user-notes.php
