I'm not exactly sure what you're trying to do, but probably:
function test_ptr($ip,$hostname){
return (trim($ip)==trim(gethostbyname($hostname)));
}
Or, alternatively, since you seem to want an error message:
function test_ptr($ip,$hostname){
$return = (bool)(trim($ip)==trim(gethostbyname($hostname)));
if(!$return) trigger_error("{$hostname}'s ip is not {$ip}");
return $return;
}
Grtz,
