CSV Export and comma separated values

Hello all,

If I log a value with commas in it the CSV export breaks due to a lack of field escaping.

aal_insert_log( array(
  'action' => 'Test Log',
  'object_type' => 'Options',
  'object_name' => 'thing,with,comma', // This is the problem
  'object_subtype' => 'Test Log'
));

I’d like to report this as a bug with the following code thank you

$output = join( ',', array_values( $columns ) ) . "\n";
foreach ( $data as $row ) {
    $output .= join( ',', $row ) . "\n";
}

This export could be refactored into perhaps?

$fp = fopen('php://output', 'wb');
fputcsv($fp, $columns );
foreach ( $data as $row ) {
    fputcsv($fp, $row );
}
fclose($fp);
