[Muff]

Guten morgen!
Problem, hab die funktion, doch er gibt immer den wert true zurück?!
Wieso?

<?
function CheckPassword($login,$password)
    {
    global $logintab,$db_sql;
    $result = $db_sql->sql_query("SELECT username, userpassword FROM $logintab WHERE username='$login' AND userpassword='$password'");
    if (! $result)
     die ("CheckPasswort fatal error: ".mysql_error() );
      
    if (mysql_num_rows($result))
      return mysql_fetch_array($result);
        
        return false;
    
}
if (CheckPassword == TRUE) 
{
echo "muh";
} 
else
{
echo "muhmuh";
}


?>

<?
function CheckPassword($login,$password) {
    global $logintab,$db_sql;
    $result = $db_sql->sql_query("SELECT username, userpassword FROM $logintab WHERE username='$login' AND userpassword='$password'");
    if (!$result) {
        die ("CheckPasswort fatal error: ".mysql_error());
    }
      
    if (mysql_num_rows($result) > 0) {
        return mysql_fetch_array($result);
    } else {
        return false;
