note 123563 added to function.gethostbyaddr

I discovered that gethostbyaddr sometimes returned the same host name with some uppercase letters in it and sometimes with all lowercase letters. example: d54c34fa1.access.example.com d54C34FA1.access.example.com This is probably not the fault of gethostbyaddr, but this can be a problem when comparing or storing, because it will give two entries instead of one. A simple solution to this is to use strtolower on the host name. ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.142 (proxied: 84.87.109.171) ---- Manual Page -- http://php.net/manual/en/function.gethostbyaddr.php Edit -- https://master.php.net/note/edit/123563 Del: integrated -- https://master.php.net/note/delete/123563/integrated Del: useless -- https://master.php.net/note/delete/123563/useless Del: bad code -- https://master.php.net/note/delete/123563/bad+code Del: spam -- https://master.php.net/note/delete/123563/spam Del: non-english -- https://master.php.net/note/delete/123563/non-english Del: in docs -- https://master.php.net/note/delete/123563/in+docs Del: other reasons-- https://master.php.net/note/delete/123563 Reject -- https://master.php.net/note/reject/123563 Search -- https://master.php.net/manage/user-notes.php
