Use $_SERVER 'php_self'. It will allow you to create script on same page where you want alert. In this way you won't have to add header.

Here's an example:

                        

                            

                                Username
                                
                            
                            

                                Password 
                                    
                            
                            

                                
                            
                        
                    


$sqluname="root";
$sqlpword="hrhk";
$database="registration";
$server="127.0.0.1";
$db_handle=mysql_connect($server,$sqluname,$sqlpword,$database);
$db_found = mysql_select_db($database, $db_handle);

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $uname = $_POST["username"];
    $pword = $_POST["password"];

    $ulength=strlen($uname);
    $plength=strlen($pword);

        if($ulength > 5){
            $sqlquery="SELECT * FROM members WHERE username='$uname' AND password='$pword'";
            $result=mysql_query($sqlquery);
            $num_rows=mysql_num_rows($result);
                if ($num_rows >0) {
                    echo "";

                    session_start();
                        $_SESSION['sid']=$uname;
                        header("location:Yahoo/yahoo.php");
                }
                else{

                    echo "";
                }
        }
        else{


            echo"";
        }

}
