Yes, can be done, but doesn't it make more sense to send the visitor back to
the original form?
$succes = ...your test goes here...
if (!$succes) {
// send back to page with loginform
header("Location: loginform.php?result=".urlencode('bad login.'));
exit;
}
// just continue here with page with samples
You can easily get the 'result' in your loginpage to display like this:
<?php
if (isset($_GET["result"])){
echo $_GET["result"];
}
?>
That way your visitor understands what is going on.

excactly.
Also, consider less usage of echo. It makes your life unneeded hard since
PHP can easily jump in and out of the output like this:
<?php
if ($sometest){
?>
massive amount of plain HTML
<?php
} else {
?>
massive amount of plain HTML
<?php
}
?>
It saves you a lot of extra work to simple 'jump back to html'.
