                 <td><?php echo $row[location];?></td>
?>

Answer 1

Maybe you query the result again like this:

$query = "SELECT * 
INTO OUTFILE '/tmp/result.csv'
FIELDS TERMINATED BY ',' 
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '\\'
LINES TERMINATED BY '\n'
FROM customers
WHERE name LIKE '%" . $term . "%'
OR location LIKE '%" . $term . "%'";

Haven't tried this yet, but this should generate a csv file you can then open or link to.

Answer 2

PHPExcel has already been suggested and I concur, this is one of the best libraries out there. One major drawback is its memory footprint, and it could be an overkill for a simple CSV export.

If you only need CSV, you may want to look into the (more low-level) built-in feature of MySQL: SELECT ... INTO OUTFILE .

It is less flexible and has a few pitfalls, but its is lightning fast compared to resorting to an external library. Most problems you may encounter with this approach have already been answered here at StackOverflow.
