note 99826 added to function.gethostbyaddr

The dns_get_record function seems to avoid timeout problems caused by gethostbyaddr() when looking up no existent records. Example below. <?php function get_host($ip){ $ptr= implode(".",array_reverse(explode(".",$ip))).".in-addr.arpa"; $host = dns_get_record($ptr,DNS_PTR); if ($host == null) return $ip; else return $host[0]['target']; } print get_host('192.168.1.5'); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 124.169.46.31 ---- Manual Page -- http://www.php.net/manual/en/function.gethostbyaddr.php Edit -- https://master.php.net/note/edit/99826 Del: integrated -- https://master.php.net/note/delete/99826/integrated Del: useless -- https://master.php.net/note/delete/99826/useless Del: bad code -- https://master.php.net/note/delete/99826/bad+code Del: spam -- https://master.php.net/note/delete/99826/spam Del: non-english -- https://master.php.net/note/delete/99826/non-english Del: in docs -- https://master.php.net/note/delete/99826/in+docs Del: other reasons-- https://master.php.net/note/delete/99826 Reject -- https://master.php.net/note/reject/99826 Search -- https://master.php.net/manage/user-notes.php
