$ipArray = explode( '.', $ipAddress );

if(( $ipArray[0] == 10 ) && 
   ( $ipArray[1] == 8 ) && 
   (( $ipArray[2] >=4 ) && ( $ipArray[2] <=5 ))) {
  echo 'Access granted';

} else {
  echo 'Get lost, ya bum!';

}

Convert the ip numbers to integers and check if the incoming ip is within range.
You can use ip2long();

[PHP] allowing access to php page by IP

2003-10-07 Thread Adam Williams 
Hello,

I want to allow access to a php page but am not sure how I should verify 
the IP once I get it.  I want to allow 10.8.4.* and 10.8.5.* to access a 
certain webpage and keep everyone else out.  I have written code to figure 
out what someone's IP is, but am not sure about how I should verify 
whether the IP is in the range of 10.8.4.* or 10.8.5.*.  Any suggestions?  
I was thinking of either using a regex (but I dunno regex so I'd have to 
learn it) to stip off the .* octect and then compare the rest of the IP 
and see if its either 10.8.4 or 10.8.5, or create a for loop and loop 
through 1-254 and cat it to the end of 10.8.4. and 10.8.5. and compare it 
to the IP they are coming from.  Any suggestions on how I should do it?

Here is the code I have to get the IP:

if (getenv("HTTP_CLIENT_IP"))
{
$ip = getenv("HTTP_CLIENT_IP");
}
elseif (getenv("HTTP_X_FORWARDED_FOR"))
{
$ip = getenv("HTTP_X_FORWARDED_FOR");
}
elseif (getenv("REMOTE_ADDR"))
{
$ip = getenv("REMOTE_ADDR");
}
else $ip = "UNKNOWN";

Thanks,
Adam
