return statements?

[nikko50]

Hello.
If a statement returns false, can I use it with the "!" to evaluate if it was successful like below. ??

function confirmUserExists($username, $password){
/ Verify that user is in database /
$q = "SELECT * FROM ".TBL_USERS." WHERE userlogin = '$username' and password='$password'";
$result = mysql_query($q, $this->connection);

  if(!$result || (mysql_numrows($result) < 1)){

     return false; //Indicates username failure
   }

 }

$userExist = $user->confirmUserExists($SESSION['userid'], $SESSION['pass']);

if(!$userExist) {
//do something } else {

do something else

}

Yes. You can also is if empty(), if !isset(), and if $var != 1, true, or whatever other match you want to check against.
