Re: [PHP-DB] Headers sent error msg on one server but not the other.....

I suggest you to activate "Output Buffering" at beggining of your code. It's
so easy and should not modify the output of your code.
This prevents your error "Headers already sent".
At the first line of your PHP code, insert "ob_start()" and in the end of
your code insert "ob_clean_flush()".

If you do not want to use "Output Buffering" you should remove any character
sent, including Cr Lf (\n\r). I think it's so hard and I don't recommend it.

Depending of your server, PHP can evaluate \n\r as nothing or evaluate \n\r
as an output.

Something is generating output before you get there - it could be as simple
as:
---
<?php
$stuff = '';
?>

<?php
$otherstuff = '';
?>
---
Did you spot it?  That's right - a carriage return was sent.  Since your
application works locally, I'd have to assume something is sending output
before your scripts even start.  Is there any kind of header, wrapper,
server-side include, or anything around the script - or perhaps you're
making use of output buffering and the server isn't allowing its use?
