mysql - PHP script not exporting as csv -

-

working on script having header sent troubles on lines allow download csv.

http://pastebin.com/6btjbri5

an error shows:

warning: cannot modify header information - headers sent (output started @ /home/briancqc/public_html/config.php:5) in /home/briancqc/public_html/export.php on line 29

warning: cannot modify header information - headers sent (output started @ /home/briancqc/public_html/config.php:5) in /home/briancqc/public_html/export.php on line 30

warning: cannot modify header information - headers sent (output started @ /home/briancqc/public_html/config.php:5) in /home/briancqc/public_html/export.php on line 31

where add <br> after every row new line starts?

how looks right now:

it goes in constant line export of rows.

check config.php file not have blank lines outside (e.g. @ end of file)
