Re: [PHP] Restricting access using IPs
Liam,
Not altogether happy with the suggestion below. It works - for now.
A more generic solution might be to replace the hard-coded 9 with a call
to strrchr() on the last 'dot' character position (minus one). Then it
should work on any properly formed IP address.
Thereafter parameterise the subnet address portion and things become
mobile/re-usable.
Regards,
=dn
Oops, wrong variable. That should be:
$substring = substr($REMOTE_ADDR,0,9);
if ($substring == '192.168.0')
{
// you're in
}

Denied
So I need to know how to write this bit:
$localip = 192.168.0.13;
so that it's the network, not just me.
I tried these but they didn't work:
$localip = 192.168.0.0;
$localip = 192.168.0.*;
$localip = 192.168.0.0/24;
Any other ideas?
Cheers

HOW doesn't it work too well? It displays a picture of a naked guy
