note 117834 added to function.gethostbyname

Always add the root . at the end or your server can add it's own suffix. example: abc.com could become abc.com.yourcompany.com if you don't use abc.com. I also find this function a litle bit limited because it doesn't tell you if the resolve failed. TO adress all those issues I use : function host2ip($host) { $host=trim($host.'.'); // clean and add root . $ip= gethostbyname($host); if($ip==$host) $ip='';// empty IP if there is no ip return $ip; } ---- Server IP: 72.52.91.14 Probable Submitter: 78.22.3.138 ---- Manual Page -- http://php.net/manual/en/function.gethostbyname.php Edit -- https://master.php.net/note/edit/117834 Del: integrated -- https://master.php.net/note/delete/117834/integrated Del: useless -- https://master.php.net/note/delete/117834/useless Del: bad code -- https://master.php.net/note/delete/117834/bad+code Del: spam -- https://master.php.net/note/delete/117834/spam Del: non-english -- https://master.php.net/note/delete/117834/non-english Del: in docs -- https://master.php.net/note/delete/117834/in+docs Del: other reasons-- https://master.php.net/note/delete/117834 Reject -- https://master.php.net/note/reject/117834 Search -- https://master.php.net/manage/user-notes.php
