if, elseif, else doesn't work?

[jpeterso2413]

For the life of me I don't know why this isn't working....

I am checking for ip addresses and I have three options. Addresses that start as 172.25. or 172.24. all others default as off-campus.

Here is my code:

print "<p>Ip =$REMOTE_ADDR";

function GetLocation()
{
if (ereg('^172.25.', $REMOTE_ADDR))
$location = "on-campus";
elseif (ereg('^172.24.', $REMOTE_ADDR))
$location = "on-campus";
else
$location = "off-campus";
return $location;
}

$location = GetLocation();

print "<p>Location = $location";

This is what is displayed:

Ip =172.24.142.***

Location = off-campus

Any Help as to why this skips my if and elseif statement?

I could be wrong, but should that format be like the below...

if (statement) {
//stuff
}
elseif (otherstatement) {
//other stuff
}
else {
//no statement needed for this
}

You have to set $REMOTE_ADDR as global inside the function.

send the ip-addr as a parameter in the function:

function GetLocation($REMOTE_ADDR)

Cool, That fixed it. The scope of PHP functions messed me up.

Thanks for the quick and valuable response.
