Answer 1

<?php
// output headers so that the file is downloaded rather than displayed
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=filename.csv');
// create a file pointer connected to the output stream
$output = fopen('php://output', 'w');
// output the column headings
//fputcsv($output, array('Column 1', 'Column 2', 'Column 3'));
// fetch the data
mysql_connect('localhost', 'user', 'pass');
mysql_select_db("database");
$rows = mysql_query('SELECT something, something, something FROM table');
// loop over the rows, outputting them
while ($row = mysql_fetch_assoc($rows)) fputcsv($output, $row);
?>

Answer 2

ok its simple in CI
Just download csv library
then
$this->db->select('*')->from('yourtabl')->where(array('your_conditions'));
$query = $this->db->get();
$this->load->helper('csv');
query_to_csv($query, TRUE, 'yourfilename.csv');
and bingo
