note 97982 added to function.ip2long

I would just like to try and clear up simply that if storing IPV4 addresses in an SQL database you should use an unsigned int (4 bytes). The easiest way to do this in PHP is to use sprintf(): $dottedFormatAddress = '127.0.0.1'; $ipv4address = sprintf("%u", ip2long($dottedFormatAddress)); Primary reasons are it's compatible with database functions like MySQL's INET_ATON & INET_NTOA (which also use unsigned int's), it's efficient, and it's the most common format used by IP lookup databases. ---- Server IP: 69.147.83.197 Probable Submitter: 78.105.235.11 ---- Manual Page -- http://www.php.net/manual/en/function.ip2long.php Edit -- https://master.php.net/note/edit/97982 Del: integrated -- https://master.php.net/note/delete/97982/integrated Del: useless -- https://master.php.net/note/delete/97982/useless Del: bad code -- https://master.php.net/note/delete/97982/bad+code Del: spam -- https://master.php.net/note/delete/97982/spam Del: non-english -- https://master.php.net/note/delete/97982/non-english Del: in docs -- https://master.php.net/note/delete/97982/in+docs Del: other reasons-- https://master.php.net/note/delete/97982 Reject -- https://master.php.net/note/reject/97982 Search -- https://master.php.net/manage/user-notes.php
