As Experts requires today i have described here XL create class. Here we will show, How to create XL file from mysql tables? Its very simple for use. Just a simple mysql query and then config your database, a XL file will be created name as today date format. Next time we will show, How to create XL from XML file. That will come very soon i think.

And here an example file name example.php

$mid_excel->WriteSQLDump($query, 'test', 'root', '', 'localhost'); //query,dbname,username,password,servername

Finally enjoy!
