I'm new to this. So I used a tutorial to write this. But it shows "Login ok.
Welcome" at once when the page loads. Here is the tutorial:
http://www.ss32.x10hosting.com/ss32/files/PHP-logins.pdf


There was an error processing your login.

}else{
?>
Login ok. Welcome ";


you will end up here if $err==1
Since you set $err=1; just before the if block begins, this is as expected.
You might find the section on if statements in the PHP manual has some
useful examples which might make things clearer:

The tutorial you are following is a bit ropey to be honest if this is the
dtandard of the code in it.
