Cannot modify header information......

Feb 1st, 2009

Warning: Cannot modify header information - headers already sent by (output started at /home/mysite/public_html/redirect_index.php:20) in /home/mysite/public_html/redirect_index.php on line 38

I've converting as asp site to php. I'm a partial numpty in asp and complete numpty in php

I keep being told this is a white space problem..... I can't see it!

The code below is a redirect: from one page to another where a Yes or No is clicked and then redirected accordingly.

The asp code was "converted" to php using a conversion prog, so anything could have happened! Maybe the sequence of events is incorrect?

Any advice greatly appreciated.

You can't have anything echoed to the screen (including whitespace) before the header() function.

<? echo $strTemp;?>
<? echo $strTemp;?>

will ensure your code goes "t*** up".

Thanks Buddie, methinks I had better bury my head in some books to get at least up to half speed on this coding lark!

You do not need all of those PHP start and end tags.

You only need one at the beginning of the PHP code and one at the end. Any blank line in between a close and start tag is being sent to the browser. Eliminate all of the unecessary PHP start and end tags and your problem will go away.
