php:how to continue execution after exiting from a php script

I am writing a web page, which searches in a table and displays the data if all is well and a message if not. The code looks roughly like this:

<?php session_start(); ?>
<html><head> ..... </head>
    <body>
         <form action="search.php" method="post"> {parameters for searching} </form
         <?php include_once('display_results.php');?>
         <?php if (isset($_SESSION['message'])) {
                   echo "<script type=\"text/javascript\">alert(\"".$_SESSION['message']."\")</script>";
                   unset($_SESSION['message']);
               } ?>
     </body>
</html>

the display_results.php looks like this:

<?php
     //query table get results build output and if there was an error call do_exit($message)

 function do_exit($message) {
    //unset objects close connections and misc finalizations
    $_SESSION['message'] = $message;
    die();
 }

My problem is that when die() is called, it seems that not only does the display_results.php script stops, but also the original php file, so even though the message is set, there is no alert. On the other hand, if I remove the die() statement, and after each do_exit() I execute return this works correctly.

Now this isn't a huge problem, I can just make it so that I call return after each do_exit() but I was wandering if there was a way to exit the script but continue with the execution of the original php file

Thanks in advance for any help you can provide.

You don't actually have to call die() at all. Just let the script come to a natural ending. I assume you return results using echo or print statements. If you need performance you can close the session so that other calls can run on it.

Why would you want to do that? Just exit a function correctly (with return). It would be possible to do: return do_exit(); and replace die() in your do_exist() function with return; or return false; (if you want to return a value).

die() (or exit()) always ends the script execution, not only the execution of one script-file or a function, that wouldn't be useful.

why don't you use return false; at the end of your function do_exit()?
