php x = 0 or y = 1 not working in if string

Question

if(strpos($drop, 'norm') !== false && $ruavalue === 0 || $ruavalue === 2) 
{
Echo "RUA: ";
$RUAresult = mysql_query("SELECT Answer FROM options"); 
echo '<form action="" method="post">';
echo "<input name="boss" type=hidden value='".$_POST['tier_two']."'>";
echo "<input name="main" type=hidden value='".$_COOKIE['ID_my_site']."'>";
echo '<input type="submit" name="ruasubmit" value="RUA!" />';
echo '</form>';
} else {
echo "You Have RUA'ed To This Boss";
}

when i use

if(strpos($drop, 'norm') !== false && $ruavalue == 0)

it works fine but i need to use

if(strpos($drop, 'norm') !== false && $ruavalue === 0 || $ruavalue === 2) 

and it is not working correctly

Answer 1

What about this:

if(strpos($drop, 'norm') !== false && ($ruavalue === 0 || $ruavalue === 2))
