Export CSV from Mysql

Question

I\'m having a bit of trouble exporting a csv file that is created from one of my mysql tables using php.

The code I\'m using prints the correct data, but I can\'t see ho

Three things to consider:

1. You're sending headers indicating that the user is going to be downloading a CSV file, but then you send create a link to download it? This isn't correct, you should be linking to this page, and then only outputting the CSV data itself after the headers.

2. MySQL has the ability to generate CSV output, and you should definitely take advantage of this instead of trying to do it yourself. You can use SELECT INTO ... OUTFILE to do this.

3. If you must create the CSV using PHP, please use fputcsv to do so. This will handle all the complications of CSV such as escaping and proper formatting. Since fputcsv writes to a file, you could either write it to a temporary file and then output it after you send your headers, or use the following trick to output it directly:

Do this after sending headers:

$fp = fopen('php://output', 'w');
while( $row = mysql_fetch_row( $export ) ) {
    fputcsv($fp, $row);
}
