Extra newlines in generated text file

[dbenson]

I'm writing a page to download a list of email addresses which are stored in a database to a text file.

From the archives I've figured out how to get IE and Netscape to properly download the file. However the file contains an extra set of newlines (\n\n) at the top of the file before my output (verified w/ od). This of course confuses apps like notepad that our clients might be using to access the downloaded data.

I've tried switching the content-type header to application/download, text/plain, text/x-plain without changing the results.

How do I prevent the extra newlines from appearing?

Thanks,

David

<?
Header("Content-Disposition: attachment; filename=address.txt");
Header("Content-type: application/octet-stream");

... get data from database ...

for ($Row = 0; $Row < $LenAddressList; $Row++) {
echo $AddressList['ADDRESS'][$Row] . "\r\n";
}
?>

Try this.

for ($Row = 0; $Row < $LenAddressList; $Row++) {
if ($AddressList[\'ADDRESS\'][$Row] != \'\'){
echo $AddressList[\'ADDRESS\'][$Row] . \"\r\n\";
}
}

In the if statement, those are 2 single quotes, not a single double quote.

If I had actually simplified my test script to something closer to what I posted I would have figured out my own problem.

The culprite is output buffering which we enable by default to gracefully handle errors, but was inserting the extra newlines. Calling ob_clean_flush() before outputing the real content fixed things.
