Im having a problem with my last account, sorry....

When trying to redirect my php page to always include "www" i use:
<?
header('Location: http://www_my_page');
exit;
?>
i get this error message:

Warning: Cannot modify header information - headers already sent by

i do not know what to do...

thanks

Be sure this is the first line of output, prior to ANY PHP header or echo statements, and before ANY HTML.

1) Post all of the code.

2) The information that wirehopper gave you is correct and is the cause of this error 99.99999999% of the time. The chances are overwhelming that you have some character that is being output before the header() command.

Watch out for white space. I dont know what type of editor your using (I use pspad) but it may have an option to show hidden characters.

Note that any single character (even a hidden one) will cause this error. The character can even be before the starting <?php tag.

If this file is included in another file, the same rules about output must be observed.

Headers must be sent prior to any output.

As ruteckycs says, even a simple

PHP Code:

<?php

can cause that error.

My suggestion is to use ob_start() and ob_end_flush() OR to redirect the user using javascript, its much simpler and works very well:

Code:

<script> document.location.href=`http://www.mypage.com`; </script>

As I said before, post all of the code. Otherwise all we can do is guess.
