So you want to allow your users to get some data directly into their excel.... no problem.
All you need to do it organize your data in rows where each data field is delimited by a comma or
some other acceptable delimiter and send the correct header to the browser.
Suppose you want to send something like :
Car Type Car Model Number of Cars
Mazda 323 5
Mazda 6 4
Mazda MPV 6
all you need to do is :
| <?php
header ("Content-type: application/csv\nContent-Disposition: \"inline; filename=Report.csv\"");
Echo"Car Type,Car Model,Number of Cars\n";
Echo"Mazda,323,5\n";
Echo"Mazda,6,4\n";
Echo"Mazda,MPV,6\n";
?> | |
Tip : It always helps to put a nice excel logo where you offer to export your data to excel format.
You can get such a logo here:

When your data is in UTF-8 you can't simply export it into excel since Excel does not support UTF-8. It took me some time to find but finally i found an example by peter kehl which you can see bellow :
UTF-16LE solution for CSV for Excel by Eugene Murai works well:
| <?php
$unicode_str_for_Excel = chr(255).chr(254).mb_convert_encoding( $utf8_str, 'UTF-16LE', 'UTF-8');
?> | |
However, then Excel on Mac OS X and also some windows doesn't identify columns properly and its puts each whole row in its own cell. In order to fix that, use TAB "\t" character as the CSV delimiter rather than comma or colon.
You may also want to use HTTP encoding header, such as
| <?php
header( "Content-type: application/vnd.ms-excel; charset=UTF-16LE" );
?> | |

As with any header that is sent, it must be sent at the begining of the file before any other content is sent. Make sure that you are not echo`ing any other content before the header is sent.
