PHP-General - Headers already sent errro
Ok I know what the problem is. My question is

does doing something like

$variable = "test";

cause problems with this:

header('Location:url');

Only if your code produces errors or warnings, which are then spit to the screen with plaintext headers.

If you do:

PHP Code:
 $a = array();

$b = $a['foo']; 


You will get a warning about the undefined index 'foo'. If your server is set up to broadcast errors to the screen, that error will show up and the headers will be printed for a plaintext/HTML document.

Spaces within your PHP code are not sent as output and won't affect headers.
