Header() issue..

[Adam]

Hello everyone, im trying to connect to a database, and depending on some of
the variables determine where to redirect the page to.

However im sure I am not grasping the concept of header(location : url) to
the fullest.
And I keept getting the dreaded:

Warning: Cannot add header information - headers already sent by (output
started by file.php) on line <line ##>.

error, so could someone let me know if there is another way to redirect this
page using PHP, basically of the variable == 1 it goes to pagea.php, if the
variable ==2 it goes to pageb.php

Pretty straight forward, and the SQL is all set up properly, just need to
forward this.

Thanks!

Headers need to be the _first_ output of PHP script - even the PHP
warning/error messages matter!! So, check if something didn't produce the
output (it actually did ;) before ...

Re: Header() issue..

I forgot to mention that there is an include file on line 1.
And that pages does produce output, is there a way around that??

If you have the relevant version of PHP, and it's not been disabled in the
server config, you can put

ob_start();

at the beginning of the code, before any output takes place. That will
let you spit headers out right at the end of the script if you want!

There's more info on this kind of thing at
