note 118841 added to function.gethostbyname

Options for the underlying resolver functions can be supplied by using the RES_OPTIONS environmental variable. (at least under Linux, see man resolv.conf) Set timeout and retries to 1 to have a maximum execution time of 1 second for the DNS lookup: <?php putenv('RES_OPTIONS=retrans:1 retry:1 timeout:1 attempts:1'); gethostbyname($something); ?> You should also use fully qualified domain names ending in a dot. This prevents the resolver from walking though all search domains and retrying the domain with the search domain appended. ---- Server IP: 72.52.91.14 Probable Submitter: 93.159.255.203 ---- Manual Page -- http://php.net/manual/en/function.gethostbyname.php Edit -- https://master.php.net/note/edit/118841 Del: integrated -- https://master.php.net/note/delete/118841/integrated Del: useless -- https://master.php.net/note/delete/118841/useless Del: bad code -- https://master.php.net/note/delete/118841/bad+code Del: spam -- https://master.php.net/note/delete/118841/spam Del: non-english -- https://master.php.net/note/delete/118841/non-english Del: in docs -- https://master.php.net/note/delete/118841/in+docs Del: other reasons-- https://master.php.net/note/delete/118841 Reject -- https://master.php.net/note/reject/118841 Search -- https://master.php.net/manage/user-notes.php
