what does "script" tag do?

@cubny Sorry, just saw your comment.

According to[0] one way of starting a block of PHP code is:

<script language="php">
        echo 'some editors (like FrontPage) don\'t
              like processing instructions';
</script>

The thing is, you can open a PHP block of code one way, and close it the other way. So

<?php
</script>

is valid (hence ========== is printed as is as the last line).
