Question

Its a very silly problem but somehow it is not working
I have a function to create a file, if it goes through with it i want it to redirect the user to X page.. in this case 1.php…. but somehow is not working :S why?

    //Creates File, populates it and redirects the user.
if (createfile($dbFile)) { 
    header('Location: 1.php');
        }

You need to exit() after sending a redirect header:

 if (createfile($dbFile)) {
     header('Location: http://yoursite.com/path/to/1.php', true, 302);
     exit();
 }

Otherwise, PHP continues to execute. If you exit(), the client receives the header right after you make the call to header().

You should also heed this warning on the PHP docs page for header():

HTTP/1.1 requires an absolute URI as argument to Location: including the scheme, hostname and absolute path, but some clients accept relative URIs. You can usually use $_SERVER['HTTP_HOST'], $_SERVER['PHP_SELF'] and dirname() to make an absolute URI from a relative one yourself:

<?php
/* Redirect to a different page in the current directory that was requested */
$host  = $_SERVER['HTTP_HOST'];
$uri   = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');
$extra = 'mypage.php';
header("Location: http://$host$uri/$extra");
exit;
?>
