export to csv

I have a page that displays data from a db2 database. I then have a button to export the data to a text file (csv). My display page works fine, no matter how many rows of data I have. It seems that if I have more than 2000 rows, then the browser displays my csv.php page, with no content. If there are less than 2000 rows, then I get the dialog box to save my file. Below is the code for my csv.php file. Any help would be greatly appreciated.

[code]
<?
