I create pages in my current PHP project by using the following template:

<?php
include 'bootstrap.php';
head();
?>

<!-- Page content here -->

<?php
foot();
?>

Is the following example an appropriate use of die()? Also, what sort of problems might this cause for me, if any?

<?php
include 'bootstrap.php';
head();

try
{
    //Simulate throwing an exception from some class
    throw new Exception('Something went wrong!');
}
catch(Exception $e)
{
    ?>
    <p>Please fix the following errors:</p>
    <p><?php echo $e->getMessage(); ?></p>
    <?php
    foot();
    die();
}

//If no exception is thrown above, continue script
doSomething();
doSomeOtherThing();

foot();
?>


?>

<?php
foot();
?>

Basically, I have a script with multiple tasks on it and I am trying to set up a graceful way to notify the user of input errors while preventing the remaining portion of the script from executing.

Thanks!
