PHP - Exit Function Early

I really hit a wall while trying to figure out how to stop my script from terminating early.
First, my website is located on an IIS server.
Second, the script I'm referring to is supposed to be some kind of a 'thread' (and I know this is not the place to use PHP but it's not my website and it's not my script - I only need to get it to work). So it basically opens in the background and stays alive by using the Sleep function inside a For loop (until some term has been met).

My problem is that the script is being terminated after about 3-5 minutes (not sure exactly after how long). I already tried adding the set_time_limit(0) and it had no effect.
Does anyone have an idea how can I solve this problem and why the set_time_limit(0) is not working?

P.S.
The server is not in Safe Mode.

hi guys..

im not sure if im in the right section but.

i have this script below and it exits BUT i would like it to exit After it applies the CSS to my Error.

i want it to display nothing except the error if there is an error.. the php is being included on the index.php page which links to the css.

this works IF i put the include after the CSS link but wondering if theres a better way.


PHP
<?php


$host = 'localhost';
$user = 'user';
$pass = 'password';
$db = 'upload';
$link = @mysqli_connect( $host, $user, $pass, $db);

if(!$link){?> 
<div id='conn_error'> <?php
echo 'There was an Error Connecting to the Server';
?>
</div><?php 

}

?>


Css
Code: [Select]
#conn_error{
background: red;
font-size: 24px;
font-family: arial;
color: white;
width: 500px;
text-align: center;
border: solid 2px black;
position: absolute;
top: 150px;
left: 30%;
padding: 2px;

}

I'm new to php and I created a user registration form. But whenever I submit the form, part of my page doesn't load. I see the "successful registration" message, but I don't see my right sidebar, footer, or my wrapper div. After searching the internet all day, I concluded it was the exit() function. But if I leave in the exit function and submit the form, all of my page loads, but the original registration form is still shown below my "successful registration" message. Can someone please help?

The code seems to cear debug until I attempt to exit after doing a while loop.

I have a script that allows a User to create a new password as part of a password re-set flow.

In my script, I store the $memberID in the Session so that when I redirect from "create_password.php" to "results.php" I still have the $memberID and can store it in the transaction log in my database.

The problem is that even though I have unset() after the redirect, it is somehow erasing the value in $_SESSION['memberID'] before the redirect, and thus I get "0" in the database when "results.php" runs?!


// Temp Password expires in 1 hour (3600 seconds).
if ((time() - $tempResetOn)>10){
// Temp Password Expired.
$_SESSION['resultsCode'] = 'PASSWORD_TEMP_PASSWORD_EXPIRED_2112';

// Set Error Source.
$_SESSION['errorPage'] = $_SERVER['SCRIPT_NAME'];

// Redirect to Outcome Page.
header("Location: " . BASE_URL . "/members/results.php");

unset($_SESSION['memberID']);

// End script.
exit();
}//End of CHECK FOR EXPIRED TEMP PASSWORD


How do I unset the Session variable - in the "create_password.php" script above - AFTER I successfully redirect and store the $memberID in the database?

Thanks,


Debbie
