INET_ATON() and INET_NTOA() in PHP?
- by blerh
I want to store IP addresses in my database, but I also need to use them throughout my application. I read about using INET_ATON() and INET_NTOA() in my MySQL queries to get a 32-bit unsigned integer out of an IP address, which is exactly what I want as it will make searching through the database faster than using char(15).
The thing is, I can't find a function that does the same sort of thing in PHP. The only thing I came across is:
http://php.net/manual/en/function.ip2long.php
So I tested it:
$ip = $_SERVER['REMOTE_ADDR'];
echo ip2long($ip);
And it outputs nothing. In the example they gave it seems to work, but then again I'm not exactly sure if ip2long() does the same thing as INET_ATON().
Does someone know a PHP function that will do this? Or even a completely new solution to storing an IP address in a database?
Thanks.
