Someone else might have suggested this, but a good way to debug any
header() related problem is to remove the call to header() and replace
it with some sort of debugging output. For example, if you had the
following script ...
if ($blah;)
{
$foo="bar";
}
header("Location: http://www.php.net/";);
?>
... you will get a parse error because of the statement on line 2. This
parse error gets output just like an echo statement would, so it creates
another error when you try to then manipulate the HTTP headers. This
error is usually the one you will see on the screen. If you don't catch
the syntax error, you might not see how it is possible that any output
occurs before the header() call.
If you replace this code with this ...
if ($blah;)
{
$foo="bar";
}
echo "[Location: http://www.php.net/]";
?>
... you will see the parse error as well as the value of the header you
were going to send (which might not be static as illustrated here) on
the screen. This can reveal some really frustrating bugs sometimes.
Of course, I am assuming your error was something like, "headers already
sent on line ...", so if that isn't the error, this might all be useless
advice. :-)

Any suggestion would be appreciated.
I have been trying for a few days and still getting
nowhere.

I'm not sure but this could be because of some errors being reported. (Thus,
"headers already sent" message...) Try turning off "error reporting" in your
php.ini (temporarily), restart your web server, and try the script again.
If it works, put everything back (in php.ini, I mean) and get rid of any
"bug" that is causing the error...

Re: [PHP] redirect without using header
Start your code with ob_start() It fires up an output buffer, does not output (and headers) until ob_end_flush() called. Put ob_end_flush() after all, before last ?> Your code might looks as follows: = Heilig (Cece) Szabolcs - [EMAIL PROTECTED] - http://www.phphost.hu = -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] redirect without using header
Hi Heilig, I have been trying to use the ob_start and ob_end_flush(), but I am not sure where to put them. I try putting just before the header() but it still produce the warning that something has been output to the browser.

The error message tells you where output was started. It says something like "output started in /path/to/file.php:XXX" where XXX is the line number of that file that created output. If you show some of your code, it'll help. Otherwise, workarounds include output buffering and javascript. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] redirect without using header
Hello! > I am getting an error by using header but I couldn't > find any part of my code that output anything before > using header. Check your included files what included before using header(); These files start with without whitespace after that? And you can use ob_start() at the start and ob_end_flush() at the end, and no problems with outputting before add headers. = Heilig (Cece) Szabolcs - [EMAIL PROTECTED] - http://www.phphost.hu = -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
