Funny IF staments.

Hi why is the following happening?

I passed the following info to this page via url.

index2.php?hostname=ppp-135-16.25-151.libero.it

The code is as follows.

$where = explode('.', $hostname);
$where = $where[count($where) - 1];

if ($where == "nl"){echo 'You are in the Netherlands.';}
if ($where == "com" || "net" ||  "org" || "edu" || "biz"){echo 'You are in the USA.';}
if ($where == "at"){echo 'You are in Austria.';}
if ($where == "au"){echo 'You are in Australia.';}
if ($where == "ca"){echo 'You are in Canada.';}
if ($where == "it"){echo 'You are in Italy.';}
if ($where == "be"){echo 'You are in Belgium.';}
if ($where == "cn"){echo 'You are in China.';}

I got:
You are in the USA.You are in Italy.

you have to restate the conditions in your if:

if ($where == "com" || $where =="net" ||  $where =="org" || $where =="edu" || $where =="biz"){echo 'You are in the USA.';}

Hey thanks, I didn't even think about that. You saved me hours!

Just out of interest, is there a notable performance drawback to the following syntax? I like the way it looks in the code, but somehow it just doesn't feel right.

<?php
if(in_array($value,array('var1','var2','var3','var4','var5')) {
  echo("something");
}
?>

Cheers

bubble i use that a lot... i don't think theres much if any slowdown... PHP's array stuff is quite fast
