IF or help

[Vivid Lust]

Hi, this is probably completely wrong but:

 

I want the page to redirect to another(shown in the code) if $select doesnt equal Positive, Negative or Netural

 

This is what i tried:

 

<?php
if($select !== "Positive")
or 
if($select !== "Negative")
or
if($select !== "Neutral")
{
header('location:feedback.php?msg=2');
}
?>

 

Please correct me!

 

And thanks in advanced!

if($select != "Positive" || $select != "Negative" || $select != "Neutral")
{
header('location:feedback.php?msg=2');
}

if (!in_array($select,array('Positive','Negative','Neutral'))) {
 header('location:feedback.php?msg=2');
 exit;
}
