PHP header not redirecting (used ob_start, ect!) [duplicate]

<?php
    ob_start();
    require("inc/connect.inc");
    if(!empty($_POST)){
        $email = "'" . $_POST["email"] . "'";
        $pass = $_POST["password"];
        $sql = "SELECT * FROM iBayMembers WHERE email=$email";
        $res =& $dbs->query($sql)->fetchRow();
        $passAcc = $res[1];
        if($pass == $passAcc){
            ob_clean();
            header("Location:www.google.com", true, 301);
            exit();
       }
    }
?>

I have done and tried everything that was suggested, including exit(), ob_flush(), ob_clean() ect. I see it returns the HTML of my page (www.google.com is just an example for this question) in console of Google dev tools, but the page is staying as is.
