Output a excel file by php

[ngocham2001]

Dear all,
I have exists excel file on server. Now, I want output the file by php. I have this code:

$file = "test.xls";
$file=basename($file);
if (file_exists($file)) {
    header('Content-Type: application/ms-excel');
    header('Content-Disposition: attachment; filename='.$file);
    ob_clean();
    flush();
    readfile($file);
    exit;
}

When I click download button, I can open file, but appear "missing css file" dialog and content of this file have replaced by special character.
Anyone help me? Thank you in advanced.

Thanks, the library used to create excel file and then export to client side. But I have already excel file and I want to output it by PHP. My problem is the excel file's content was replaced by CSS file in html.. :(

So you need to read the cells in the excel and dump tables.

E.g. read excel cell1

table
--row
---excel value
--closerow
close table

etc.
