Yes, I agree it's a workaround, but sometimes it's required for code readibility (and sanity! :) For example, what if I have multiple pages in one file, with a switch-case, and some need to redirect, but there's a page header and footer? For example:

<?php
include('includefile.php');
outputheader();
switch($_GET['page']){
 case 'foo':
 //Output something here
 break;
 case 'bar':
 //Redirect here
 break
}
outputfooter();
?>

The only way would be to do the footer and header on only pages that need them, which can be lived with for a few pages, but imagine a few hundred, or thousand! Sometimes, a quick hack is good IMO.

Do you understand that this is a workaround and if you coded correctly
you wouldn't need it? 

Output buffering to enable a header() redirect later in your code is
almost never needed if you code correctly. Think about it: if you're
going to redirect to a new page, why would you have output!?

Try putting:
ob_start();
at the top of your file (before ANY output is done).

No. You have to send header information before you output anything


even-


before the <html>. On your document, you have to put it before what is

currently line 12.

Any ideas? Does this only work in the <head></head>?

header("Location:  http://www.domain.com/admin.php
<http://www.domain.com/admin.php> ");



if you _really_ need to use your syntax, you could



function redirect($uri) { header("Location: ".$uri); }
